6:25 caused some confusion. My reasoning as to why Miranda isn't a captured moon isn't solely based on the fact that it is prograde in isolation (which in retrospect I should have emphasized that and explained that more clearly in the video) that is just one of the facts that strongly suggests that it isn't in the specific context, the assumption of it not being captured is also based on the fact that it's composition is very similar to the rest of the major moons of Uranus, meaning that it almost certainly to very likely formed in the same region as them along with Uranus which on top of that also predicts a prograde orbit. Essentially that means that you can be suspicious about an object almost certainly being a captured one only when it is retrograde, while when it's prograde the chances significantly drop off as then it can be either way in that case if that is the only piece of information that you have, since when the moons of an object form around the object they are orbiting they are prograde (the moons in the Solar System suggest that strongly), the similar composition on top of a not extremely deviating inclination but just a puzzling one and the direction of movement which is also prograde for the rest of the major moons of Uranus suggest the same region of formation for Miranda and Uranus. Of course, not all captured moons are retrograde, some of them can indeed be also prograde but in the specific context of Miranda the prograde orbit is just another piece of evidence that strongly suggests that it is not captured. To simplify this even further, all non-captured moons are prograde while not all captured moons are non-prograde. Now it makes even more sense to think that Miranda isn't captured when on top of the prograde orbit which every other major moon of Uranus has you factor in the similarity in the composition with the rest of the major moons, and then to top it off factor in that the orbital inclination is not even close to the range of the moons that are certainly captured, it just deviates from the average for a non-captured moon but not to the extent at which you can conclude with any certainty that it is captured, because of that the conclusion that Miranda is not captured is strongly supported.
A bit off topic but i have a question that was bothering me for a while. In the future when HOPEFULLY we will try to colonize other places in our solar system we would face extremely cold temp. Like on europa moon. So the question is, how can we shield a human from such low temperatures? The heat escapes in 3 ways and the main problem would be convection i guess. So if we will make suits well isolated with good materials will it help? Im only 15 and english is not my first language so, im sorry for any mistakes
Uranus and Neptune don't get enough attention. We give Jupiter and Saturn a lot of attention, while the two blue giants get ignored. Its likely that a lot of exoplanets are similar to Uranus and Neptune, so learning about them would be useful.
@Arnoldo Junkes The name stigma doesn't exist in languages outside English, and we still don't talk about Uranus more. The planet simply looks boring and has never been visited by an orbiter.
Neptune gets some more attention, because apart from its deep blue color Triton is an interesting moon, though it's likely a captured TNO. If it weren't for Triton, Neptune would be the most ignored. But right now, it's Uranus, even though it's exciting in its own right. It just looks very monotone in apparence and the lack of standout moons doesn't add to exitement. I don't expect any missions to the Uranus system in the near-future. Neptune could get a New Horizons 2 type mission to study Triton, but even that seems far-fetched at this point.
@Hei Dinglepop You make some good points, but Trident is a mission to mainly study Triton, not Neptune. A flyby mission of the moon kind of like when New Horizons flew past Pluto. It seems too much of a duplication of NH. Based of current knowledge alone, Triton is quite similar to Pluto in terms of composition, size and its thin atmosphere. Do we really expect to find something significantly different there to justify billions of dollars spent on a mission like that..
As others have said, proximity plays a big part in this. Mars is not the most exciting world in the solar system, but we send so many spacecraft there because it's close to us.
Standing on one of Uranus' or Neptune's moons would be glorious. You'd be standing on a rough ice terrain, looking up at the Sun that's a bit dimmer than here on Earth and right beside you, you'd see a gigantic blue planet.
Honestly that planet freaks me out for some reason. You have a bright pale, featureless blue sphere floating in the void and it feels like its staring at you like a giant eyeball.

@@KC______ It's just a transliteration of the Greek word for "sky", Ouranos, which becomes Uranus in Roman spelling. When the planets were named, many more people had a classical education so were familiar with Greek and Roman language and mythology (from which all the planets were named). When I was in school everyone just said "your Ain us" and there were no raised eyebrows and I didn't even notice the jokes til much later. Then some people started saying "Urine us" instead, but that of course caused its own jokes. I think the former pronunciation is more natural for English. I've seen the jokes in Spanish too because that -us Roman ending becomes -o in modern Spanish, thus Urano still has an "ano" in it, as also with English, etc. speakers who say things like "Tengo treinta anos" and leave off the tilde (~) since "año" is from Latin annus (year), while "ano" is from anus (the Spanish letter ñ originated as a shorthand for a double n (nn) that had acquired that "ny" sound), with the root meaning a "ring" (cf. "annular eclipse" in English). In Portuguese too, we see the (~) used to represent a dropped "n" (e.g. são < santo < sanctus). In old manuscripts, a line on top of a letter was used generally as an abbreviation symbol. So we can laugh and and also appreciate the language issues and of course the wonders of the natural world. The planet's name Ουρανός is originally and still (in Greek) pronounced Oo-rah-NOS, meaning "sky", and there's no double entendres there, only with the Roman spelling of the last two syllables. In the nineteenth and early twentieth century the term "Uranian" was also used as a euphemism for gay (homosexual) due to Plato's discourse on "ouranios eros" in the Symposium, which was contrasted with "pandemos eros". As a result, Gilbert and Sullivan's plays could get a lot of laughs from saying that someone might be "a tad Platonic", where Platonic did not mean "platonic" in the modern sense, but the eros that Plato discussed. Things change over time. Probably only a few historians nowadays recall those former meanings. Just as it would seem that there is no controversy over the name Ganymede for Jupiter's largest moon.

Lol I just came back Also, Titania has almost non-existent atmosphere, so as I said, it doesn’t have an atmosphere, the only such moons to have such an “air” atmosphere are, triton, titan, although triton have an extremely thin atmosphere compared to earth’s, but has the ability to generate winds and produce triton clouds, it’s atmosphere pressure is comparable to mars atmosphere Only titan have an earth-like atmosphere
I would like to see a comparison of magnetic fields between moons of solar system, It's afterall a very good thing to have such shielding even though it would be inadequate for humans.
Hello! I am a visitor from the year 2093, where time travel exists. I'm just here to say that in my year, they finally changed the name of the planet Uranus. *They changed it to Urectom*
@@Galaxius2117 yeah… they’ve been continuously lowering NASA’s budget. They’d rather spend trillions of dollars on the military instead of exploring the universe. It’s really sad to see.
If you were to jump off that 20 km cliff, Verona Rupes, you would spend almost 12 minutes in free fall until you hit the ground at 56 m/s, roughly the speed of a car driving on a highway.
Thank you so much for this wonderful work of yours. I find Uranus the most fascinating planet in our solar system and it deserves a lot of attention and study. I'm sure we can learn a lot from it. On top of the planet itself there are the Moons which need to be studied more thoroughly.
The reason the retrograde orbits have nominally extreme inclinations is just a numerical illusion, because their inclinations are between 90° and 180° by definition, with 180° the inclination of a retrograde orbit perfectly aligned with the equator, that is the 0° orbit taken in the opposite direction. The angle between the equator and the plane of a retrograde orbit is 180° minus that orbit's inclination. With that in mind, the retrograde orbits are not extremely inclined any more. For instance XVII Sycorax with 159° orbital inclination has its plane only 21° (=180°-159°) tilted wrt the equator of Uranus: that's much less than the 57° of prograde XXIII Margaret.
it's not funny. But sad. (i mean this generation of pervert and PH raised people, it's not funny at all, but annoying, disturbing, sad, and perverted, I hope these kind of people and generation ends, they are really like children in adult bodies)
20:46 is why planetary scientists refer to Earth’s moon as Luna, so that it doesn’t get confused with “the Moon” of Earth and “the moon” they’re actually talking about. When talking about round moons, nobody mentions Uranus’ moons. When I try to list the names of spherical moons, many prominent examples come to mind. But I still forget that Uranus even has spherical moons because they’re so overlooked. Earth has one cool moon, Jupiter has a whopping four Galilean moons all being awesome, Saturn has two cool moons with Titan and Enceladus, Neptune has one cool moon with Triton, and Pluto has one cool moon with Charon. All of these moons stand out in one way or another. Uranus’ moons are all pretty bland. Saturn has some bland moons too like Rhea, Tethys, and Dione, and nobody talks about these either because Saturn has better ones. Many planets have at least one good moon, but Uranus really got slim pickings. Miranda is kind of cool, and having the steepest cliff in the solar system definitely earns it points. Even Uranus itself is probably the most ignored of the classical planets. It’s more interesting than Mercury in my opinion, but Mercury got more missions to it. Venus got a handful of missions, Mars got a dozen, Jupiter and Saturn both got a dozen, Pluto got only one mission, but it was the most popular mission in NASA history, and while Neptune only got one mission as well, it’s talked about more than Uranus, probably because of its significant relationship with the Kuiper Belt. But I think Uranus and Neptune both deserve more missions. I really like the topic of this video and the title fits the bill. I often forget about them, but as bland as they are, they-and Uranus-are still prominent members of the solar system and would be cool places to return to. Great video! 👍🏻
Oh, man, this is great! Hey, as long as you don't make me smell Uranus. I don't get it. I'm sorry, Fry, but astronomers renamed Uranus in 2620 to end that stupid joke once and for all.. Oh. What's it called now? Urectum.
6:25 - Re: retrograde orbit Astronomical layman here, but wouldn't a captured moon's chances of having a retrograde orbit be roughly 50/50? I understand any rogue moon has a small window regarding angle of approach, in becoming a captured moon (instead of being flung out, or colliding). But even factoring this in, it seems like a retrograde orbit would mostly depend on whether a rogue moon crosses in front of, or behind, the planet's path before being captured. Am I missing something?
Quite a lot to explain here. My reasoning as to why Miranda isn't a captured moon isn't solely based on the fact that it is prograde in isolation (which in retrospect I should have emphasized that and explained that more clearly in the video) that is just one of the facts that strongly suggests that it isn't in the specific context, the assumption of it not being captured is also based on the fact that it's composition is very similar to the rest of the major moons of Uranus, meaning that it almost certainly to very likely formed in the same region as them along with Uranus which on top of that also predicts a prograde orbit. Essentially that means that you can be suspicious about an object almost certainly being a captured one only when it is retrograde, while when it's prograde the chances significantly drop off as then it can be either way if that is the only piece of information that you have, since when the moons of an object form around the object they are orbiting they are prograde, the similar composition on top of a relatively similar inclination and the same direction of movement which is always prograde suggest the same region of formation and that all non-captured moons are prograde as they always display that direction in those cases, but not all captured moons are retrograde, some of them can indeed be also prograde. To simplify this even further, all non-captured moons are prograde while not all captured moons are non-prograde. Now it makes even more sense to think that Miranda isn't captured when on top of the prograde orbit which every other major moon of Uranus has you factor in the similarity in the composition with the rest of the major moons, and then to top it off factor in that the orbital inclination is not even close to the range of the moons that are certainly captured, it just deviates from the average but not to the extent at which you can conclude with any certainty that it is captured, because of that the conclusion that Miranda is not captured is strongly supported. Now as for the chances being overall 50% of a captured object having a retrograde orbit I highly doubt it. Chances can predict the outcome of situations on a general scale, if the chances for a flipped coin to land tails is close to 50% (which it is) then the outcome of that will be that if I flip a coin enough times roughly 50% of it will land tails, if the chance is close to 70% landing tails (which in reality it isn't but for the sake of the argument let's pretend that it is) the outcome of that is that if I flip a coin enough times 70% of it will land tails, pretty simple. So if the chances for a captured moon having a retrograde orbit were 50% the outcome should be that 50% of the captured moons are retrograde or at least close to 50%, but the data doesn't suggest that even in a very generous calculation. Out of 205 known moons of planets, 121 are retrograde, already assuming that all 205 are captured (they aren't) that would put the percentage of retrograde moons at 60%. But in order to get a number closer to actually captured satellites, we are going to need at least some line, in my estimation, anything that is 20 degrees and above in orbital inclination is in the vast majority of the cases really far away from the object it is orbiting, irregular in shape, and generally suggests that it is captured, this line encompasses some prograde orbit objects as well because of that. In that case, roughly 144 moons are captured which means that 70% of moons of planets in the Solar System are captured, of those 144, 121 are retrograde, meaning that roughly 84% of captured moons are retrograde. Also pretty much all retrograde orbit objects have an orbital inclination above 20 degrees, meaning that all non-captured moons are then categorized as prograde. Let's do it with another line, irregularity, let's say that all irregularly shaped moons are captured (which is a stretch) on top of all retrograde orbit objects being captured (which is certainly true), then out of 185 irregularly shaped moons, 121 are retrograde, meaning that 65% of captured moons are retrograde. If we take the average between the two calculations with two differently posed lines, then it would mean that approximately 74.5% of moons are captured. No matter how you slice it the data always suggest that significantly above 50% of the moons that are captured are retrograde, meaning that the chance most likely isn't close to 50/50 for a moon to be retrograde, as the vastly different outcomes from 50/50 suggest more strongly rather that the chances are different not that it's a coincidence or a lucky succession of events, especially when you consider how it's sorted. This means that for some reason that the majority of the captured moons are retrograde, currently, the exact reason for this is not known, interestingly though all prograde orbit objects that seem to be captured are all in the inner part of the hill-sphere of the object they are orbiting, while all retrograde objects (all captured) are on average much farther away and seem to be on the outer parts of the hill-sphere of the object they are orbiting, suggesting that retrograde orbits are usually more stable than prograde orbit objects while on the outer parts of the hill-sphere and prograde orbit objects are more stable in the inner part of the hill-sphere, although that isn't known certainly that is what is being suggested by the data, still whatever the case is even if that is true the evidence for Miranda being non-captured significantly out-weighs the opposing evidence.
@@DrekslerAstral - I see. Very interesting. I wonder then, if it has to do with the angle of applied force in relation to the trajectory of the object being captured. If one were to visualize the angle of the two, that is the direction of gravitational pull of the captor and the the trajectory of an object, while that angle is constantly changing as both objects are in motion... it would seem that one approach (crossing behind the planet?) would have the angle wider for a longer span of time than the other approach (crossing in front of the planet). And with the wider angle for the longer duration, the more likely it is that a captured object's momentum can be sufficiently cancelled out to allow for its capture (instead of simply deflecting it's path). Thank you for the thorough and well-sorted response.
@@Karevamari same. I reccomend David Butler's channel if you ever heard of him? His playlists "how far is it", "how small is it" and "how fast is it" have long videos like this and go over the history of how we discovered measuring distant objects in astronomy, quantum physics and relativity. Also sometimes John Michael Godier has long relaxing jazz radio voice videos about fermi paradox, new discoveries and great questions for sleeping. Same with Isaac Arthur and Anton Petrov's long compilation videos.
Great video, so much detail! It's so bizarre that even the moons maintain a perpendicular orbit... It would have to have been early on, to be knocked over...but why wouldn't some moons stay in orbit with the sun's plane?
Good reporting and i love your graphics. Very nice. A little help with your grammar. We use "farther" when we are referring to an actual distance. For example, "The moons farther from Saturn have more declination from the plane of ecliptic." Use "Further" for everything else, as in, "To further his education, Thomas signed up for an apprenticeship down at the machine shop." Or "Stranding my wife at the boat docks was the furthest idea from my mind."
I get the feeling that the moon Miranda is actually the core of a planet. This hypothetical planet must have been impacted by a large object that ended up ejecting the outer core, mantle and crust of the planet leaving the small sphere we have now.
Why would the moons also follow the axial tilt after a collision? I did a simulation and the moons remained in their same orbital plane, only the planets equator shifted. I probably messed up the simulation. I'm just wondering. I know it's a two year old video.

A surprise to be sure, but a welcome one
Been watching godier's channels for years, as well as Astrum and SEA, but this one is new to me
Here's a man of taste
@@stevencoardvenice What about ParallaxNick?
Titania has quite a thick atmosphere relatively speaking. Also Titania and Oberon rank in the top 10 largest moons and seem to be often overlooked
It’s not, it’s basically vacuum in their surface
Lol I just came back
Also, Titania has almost non-existent atmosphere, so as I said, it doesn’t have an atmosphere, the only such moons to have such an “air” atmosphere are, triton, titan,
although triton have an extremely thin atmosphere compared to earth’s, but has the ability to generate winds and produce triton clouds, it’s atmosphere pressure is comparable to mars atmosphere
Only titan have an earth-like atmosphere
Just discovered this channel today. You earned a sub.
"Uranus so big, there's moons orbiting it."
Excellent animations to portray the message.
Love this channel! Always a nice surprise to see a new video in my subs!

Hello! I am a visitor from the year 2093, where time travel exists. I'm just here to say that in my year, they finally changed the name of the planet Uranus. *They changed it to Urectom*
Urectum? Damn near killed him
We need orbiter missions for both Uranus and Neptune
Agreed
Good news, NASA is sending an orbiter to Uranus in the 2030’s as a flagship mission. (Like the same level as the mars 2020 mission and the JWST)
@@rustyshackleford234 let's just hope they don't cancel the mission. at the very least, let's hope they only delay it instead of cancelling it.

Bro I would never forget about Uranus' moons. How dare you.
Umbriel is my favorite! Something about that crater Wunda is just so enticing..
If you were to jump off that 20 km cliff, Verona Rupes, you would spend almost 12 minutes in free fall until you hit the ground at 56 m/s, roughly the speed of a car driving on a highway.
Here I was thinking that Uranus only had two moons. Left cheek and right cheek.

One of these days, I'll not chuckle like a child at the name "Uranus".

Thank you so much for this wonderful work of yours. I find Uranus the most fascinating planet in our solar system and it deserves a lot of attention and study. I'm sure we can learn a lot from it. On top of the planet itself there are the Moons which need to be studied more thoroughly.
Found your channel through a comment you left on V101.... someone said you’re a “space youtuber” so I had to check it out!!! Sweet!!
Some parts of Uranus' moons contain more craters than others
Moons don't follow the ecliptic pretty well. That means Solar Eclipses are pretty rare on Uranus and only happens on Equinoxes.
The reason the retrograde orbits have nominally extreme inclinations is just a numerical illusion, because their inclinations are between 90° and 180° by definition, with 180° the inclination of a retrograde orbit perfectly aligned with the equator, that is the 0° orbit taken in the opposite direction. The angle between the equator and the plane of a retrograde orbit is 180° minus that orbit's inclination. With that in mind, the retrograde orbits are not extremely inclined any more. For instance XVII Sycorax with 159° orbital inclination has its plane only 21° (=180°-159°) tilted wrt the equator of Uranus: that's much less than the 57° of prograde XXIII Margaret.
The man the myth the legend is back
Forgotten Moons of Uranus
Dirty Minded Children: Oh where did I miss?
Scientists: SHUT UP!
it's not funny. But sad. (i mean this generation of pervert and PH raised people, it's not funny at all, but annoying, disturbing, sad, and perverted, I hope these kind of people and generation ends, they are really like children in adult bodies)
Uranus is so intriguing.
Everytime he says " Retrograde Orbits" Do 5 push-ups. :)
I attempted your challenge, and couldn't do it anymore after the 3rd time he said it
That was easy, it would have been harder if it was, for every time he says Uranus.
Even harder with moon(s).
Amazing !!🌠 Relaxing To watch Your Videos and Learn..Keep It up🌠
Very informative video, thank you!
*No problem.*
There is a little bit of Uranus among the advertisments
20:46 is why planetary scientists refer to Earth’s moon as Luna, so that it doesn’t get confused with “the Moon” of Earth and “the moon” they’re actually talking about.
When talking about round moons, nobody mentions Uranus’ moons. When I try to list the names of spherical moons, many prominent examples come to mind. But I still forget that Uranus even has spherical moons because they’re so overlooked. Earth has one cool moon, Jupiter has a whopping four Galilean moons all being awesome, Saturn has two cool moons with Titan and Enceladus, Neptune has one cool moon with Triton, and Pluto has one cool moon with Charon. All of these moons stand out in one way or another. Uranus’ moons are all pretty bland. Saturn has some bland moons too like Rhea, Tethys, and Dione, and nobody talks about these either because Saturn has better ones. Many planets have at least one good moon, but Uranus really got slim pickings. Miranda is kind of cool, and having the steepest cliff in the solar system definitely earns it points.
Even Uranus itself is probably the most ignored of the classical planets. It’s more interesting than Mercury in my opinion, but Mercury got more missions to it. Venus got a handful of missions, Mars got a dozen, Jupiter and Saturn both got a dozen, Pluto got only one mission, but it was the most popular mission in NASA history, and while Neptune only got one mission as well, it’s talked about more than Uranus, probably because of its significant relationship with the Kuiper Belt. But I think Uranus and Neptune both deserve more missions.
I really like the topic of this video and the title fits the bill. I often forget about them, but as bland as they are, they-and Uranus-are still prominent members of the solar system and would be cool places to return to.
Great video! 👍🏻
my favorite moons frfr
I had totally forgotten about those photos...
"Not super exciting"
That's what makes them so exciting. Why is the Uranian system so seemingly featureless?

What about the one with the giant crack running right down the middle of it?
6:25 - Re: retrograde orbit
Astronomical layman here, but wouldn't a captured moon's chances of having a retrograde orbit be roughly 50/50? I understand any rogue moon has a small window regarding angle of approach, in becoming a captured moon (instead of being flung out, or colliding). But even factoring this in, it seems like a retrograde orbit would mostly depend on whether a rogue moon crosses in front of, or behind, the planet's path before being captured. Am I missing something?
Quite a lot to explain here. My reasoning as to why Miranda isn't a captured moon isn't solely based on the fact that it is prograde in isolation (which in retrospect I should have emphasized that and explained that more clearly in the video) that is just one of the facts that strongly suggests that it isn't in the specific context, the assumption of it not being captured is also based on the fact that it's composition is very similar to the rest of the major moons of Uranus, meaning that it almost certainly to very likely formed in the same region as them along with Uranus which on top of that also predicts a prograde orbit. Essentially that means that you can be suspicious about an object almost certainly being a captured one only when it is retrograde, while when it's prograde the chances significantly drop off as then it can be either way if that is the only piece of information that you have, since when the moons of an object form around the object they are orbiting they are prograde, the similar composition on top of a relatively similar inclination and the same direction of movement which is always prograde suggest the same region of formation and that all non-captured moons are prograde as they always display that direction in those cases, but not all captured moons are retrograde, some of them can indeed be also prograde. To simplify this even further, all non-captured moons are prograde while not all captured moons are non-prograde. Now it makes even more sense to think that Miranda isn't captured when on top of the prograde orbit which every other major moon of Uranus has you factor in the similarity in the composition with the rest of the major moons, and then to top it off factor in that the orbital inclination is not even close to the range of the moons that are certainly captured, it just deviates from the average but not to the extent at which you can conclude with any certainty that it is captured, because of that the conclusion that Miranda is not captured is strongly supported.
Now as for the chances being overall 50% of a captured object having a retrograde orbit I highly doubt it. Chances can predict the outcome of situations on a general scale, if the chances for a flipped coin to land tails is close to 50% (which it is) then the outcome of that will be that if I flip a coin enough times roughly 50% of it will land tails, if the chance is close to 70% landing tails (which in reality it isn't but for the sake of the argument let's pretend that it is) the outcome of that is that if I flip a coin enough times 70% of it will land tails, pretty simple. So if the chances for a captured moon having a retrograde orbit were 50% the outcome should be that 50% of the captured moons are retrograde or at least close to 50%, but the data doesn't suggest that even in a very generous calculation. Out of 205 known moons of planets, 121 are retrograde, already assuming that all 205 are captured (they aren't) that would put the percentage of retrograde moons at 60%. But in order to get a number closer to actually captured satellites, we are going to need at least some line, in my estimation, anything that is 20 degrees and above in orbital inclination is in the vast majority of the cases really far away from the object it is orbiting, irregular in shape, and generally suggests that it is captured, this line encompasses some prograde orbit objects as well because of that. In that case, roughly 144 moons are captured which means that 70% of moons of planets in the Solar System are captured, of those 144, 121 are retrograde, meaning that roughly 84% of captured moons are retrograde. Also pretty much all retrograde orbit objects have an orbital inclination above 20 degrees, meaning that all non-captured moons are then categorized as prograde. Let's do it with another line, irregularity, let's say that all irregularly shaped moons are captured (which is a stretch) on top of all retrograde orbit objects being captured (which is certainly true), then out of 185 irregularly shaped moons, 121 are retrograde, meaning that 65% of captured moons are retrograde. If we take the average between the two calculations with two differently posed lines, then it would mean that approximately 74.5% of moons are captured. No matter how you slice it the data always suggest that significantly above 50% of the moons that are captured are retrograde, meaning that the chance most likely isn't close to 50/50 for a moon to be retrograde, as the vastly different outcomes from 50/50 suggest more strongly rather that the chances are different not that it's a coincidence or a lucky succession of events, especially when you consider how it's sorted. This means that for some reason that the majority of the captured moons are retrograde, currently, the exact reason for this is not known, interestingly though all prograde orbit objects that seem to be captured are all in the inner part of the hill-sphere of the object they are orbiting, while all retrograde objects (all captured) are on average much farther away and seem to be on the outer parts of the hill-sphere of the object they are orbiting, suggesting that retrograde orbits are usually more stable than prograde orbit objects while on the outer parts of the hill-sphere and prograde orbit objects are more stable in the inner part of the hill-sphere, although that isn't known certainly that is what is being suggested by the data, still whatever the case is even if that is true the evidence for Miranda being non-captured significantly out-weighs the opposing evidence.
@@DrekslerAstral - I see. Very interesting. I wonder then, if it has to do with the angle of applied force in relation to the trajectory of the object being captured. If one were to visualize the angle of the two, that is the direction of gravitational pull of the captor and the the trajectory of an object, while that angle is constantly changing as both objects are in motion... it would seem that one approach (crossing behind the planet?) would have the angle wider for a longer span of time than the other approach (crossing in front of the planet). And with the wider angle for the longer duration, the more likely it is that a captured object's momentum can be sufficiently cancelled out to allow for its capture (instead of simply deflecting it's path).
Thank you for the thorough and well-sorted response.

Also sometimes John Michael Godier has long relaxing jazz radio voice videos about fermi paradox, new discoveries and great questions for sleeping. Same with Isaac Arthur and Anton Petrov's long compilation videos.

Great video, so much detail!
It's so bizarre that even the moons maintain a perpendicular orbit...
It would have to have been early on, to be knocked over...but why wouldn't some moons stay in orbit with the sun's plane?
Good reporting and i love your graphics. Very nice. A little help with your grammar. We use "farther" when we are referring to an actual distance. For example, "The moons farther from Saturn have more declination from the plane of ecliptic." Use "Further" for everything else, as in, "To further his education, Thomas signed up for an apprenticeship down at the machine shop." Or "Stranding my wife at the boat docks was the furthest idea from my mind."
Kind of makes me feel like exploring Uranus's moons.
I think Miranda got hit by some other large asteroid knocking it off it's orbit. The scarring on it's surface seems appropriate for this as well.
in fact, it was completely decimated to the point that when the dust settled, the surface looked like it was made by frankenstien
The surface likely was so messed up as well because Miranda could've gotten torn to pieces, and then it all came back together under its own gravity.
How many moons have you done with Uranus?
About time the "lesser" moons of the solar system get some love and attention.
This is probably way off base, but is it at all possible the tilt of Uranus is due to it being a rogue planet captured by the Sun?
No just no
If it was captured then it would have probably destabilized Neptune’s orbit while it was settling into its current orbit, so no
Finalmente, le lune di Urano spiegate! Grazie mille, Signor Astral!
Great video! There’s not enough info on Neptune and Uranus 👌🏻
I get the feeling that the moon Miranda is actually the core of a planet. This hypothetical planet must have been impacted by a large object that ended up ejecting the outer core, mantle and crust of the planet leaving the small sphere we have now.
"Balls"? Do you mean hemispheres?
If Uranus' tilt is due to an impact, why did the rings also tilt?
They seriously need to call this planet something else especially after they discovered that it leaks gas into the universe
lol
12:59 That's so cute i didn't know Ariel and Umbriel we're nearly the same size and mass
What about "Forgotten Moons of Neptune"?
All the moons of Neptune except Triton are forgotten
They can be found in Atlantis.
Well, you can imagine my disappointment when I was hoping that this was going to be a good space channel
Can we crash the moons into Uranus it would hurt but why not
Excellent video
1:12 why does Io look like Uranus?
Imagine standing in triton or titania....
I could never forget the moons circling Uranus
Why would the moons also follow the axial tilt after a collision? I did a simulation and the moons remained in their same orbital plane, only the planets equator shifted. I probably messed up the simulation. I'm just wondering. I know it's a two year old video.
Uranus doesn't get enough shine
