I love Pluto regardless. And let's face it Pluto doesn't know or care how we classify it.
Pluto knows. He knows.
They do care. I've seen a documentary about it. Was called Rick and Morty.
Pluto doesnt care about your feelings.
@@et34t34fdf erm yes that's exactly what I said. Pluto doesn't care. Thank you.
@@5Andysalive I've seen it. Love Rick and Morty
Humans: Pluto deserves to be a planet!
Makemake, Ceres, Sedna, Eris: *Am I a joke to you?*
Rude
@Stellvia Heonheim He meant that Pluto is a part of a belt with many similar objects whitin the belt. It's not big enough to force objects it moves with in the belt to stick to it with gravity and clear the orbit.
@Stellvia Heonheim no orbit around proxima centauri
I see nothing wrong with calling them all planets, let's just have 100 planets in the solar system.
@@david5davidable I don't see Pluto colliding with any more asteroids than Earth or Jupiter do, that in fact means it has cleared it's path.
Don't worry pluto, you will always be a planet to me. A dwarf planet, but a planet nonetheless
I heard that. We prefer to be called 'little' planets thanks
Pluto does not deserve to be a planet I mean 1/5 the mass of the sun...
The plutonians are probably mad that their world is no longer considered a major planet.
@Davvy Jannes Pluto is a bit less than 1/5 the mass of Earth's moon. But Ganymede and Titan are larger than Mercury, so...
until you see a thousand other meteoroids right behind it that all look the same
People get so emotional about Pluto, but Ceres had it worse. I love the dwarf planet category, it just proves how much richer than we thought our solar system is, and it also gave Ceres and the other dwarf planets a nice place of their own.
it does sadden me that Ceres doesn't get mentioned by many..
And ceres even has a friend in the asteroid belt: hygiea. 444 km in diameter, just big enough to be spherical.
Being a dwarf planet does not take anything away from pluto it's still a magnificent celestial body and I love it even if they call it a whale in the sky next.
There are still so many people who do not understand why Pluto was reclassified even 13 years after the change was made. Thanks for making this video to help educate them.
It's a planet to me okay
Oh, I think most of us understood. It's just that some of us object...
@@baruchben-david4196 Because people can't handle with stuff that they once learned and what then turned out to be wrong.
I think they feel betrayed or something and deny the new information, because they made the wrong knowledge to their own
and feel someone is trying to steal something from them. I think that's why religion, superstition, astrology, supernaturalism and homeopathy are so hard to kill,
even if we actually know through logic and experiments that it is all nonsense. People tend to be pretty stubborn.
It was a nasa conspiracy orchestrated by the cia to cause mass division between pluto truthers and the dwarfers, and ultimate goal is a form population control when these two groups inevitably go to war.
@@OxKing Except it was never wrong to call Pluto a planet. It was the rules of classification that changed. They could have said that only the gas giants count as true planets and the rest are dwarfs. Would that be anymore correct?
So if Pluto was a planet this would be the solar system:
Mercury
Venus
Earth
The Moon
Mars
Ceres
Jupiter
Ganymade
Callisto
Io
Europa
Saturn
Titan
Enceladus
Rhea
Uranus
Neptune
Triton
Pluto
Charon
Eris
Makemake
Yes, very very correct my good friend.
Awesome 👍
i think i'll just prefer the main 8-line Planets instead..
You claim that all of these would be planets? But many of them are moons and do not orbit the Sun, but a planet.
Everybody's looking at this wrong- Pluto isn't going to "clear it's orbit"; it's hanging with the rest of the asteroids in it's crib, they're buds.
Pluto's classification always been a mystery for me and thanks to this video, I've got answers to most of my questions. Thanks Alex, for this video. :)
“Uranis was discovered which was revolutionary”.
Aren’t all planets “revolutionary”?
Hoho! 😝
No...because the others that were discovered before can be seen in the sky.
Also, it's existence and location was theorized with maths. That same technique was used to theorize the existence of Neptune. Neptune's existence was verified (discovered) in a single night. Because they knew exactly where to point the telescope.
@@tylerdurden3722 I believe David made a play on words, hence the quotations
@@theklarsen1 aaah...stupid me
pluto will always be a planet in our hearts
Fact
After New Horizons, Pluto became the most beautiful object in the Solar System.
Saturn is still the most beautiful to me.
I grew up being taught in school that Pluto was a planet, dwarf or not, it'll always be a planet to me. Pluto is the Tyrion Lannister of our planets, cast out of his family just for being a dwarf, he didn't ask to be made this way when the solar system was forming!
Pluto fans should go visit Lowell Observatory in Flaggstaff, AZ. You can get up close to the telescope used to find Pluto. The guy manually tracked his fixed point for hours at a time to get the pictures on the glass plates (you can see those also). Its worth the trip! Really fun and informative, not to mention it's a beautiful place. And it's only 30 minutes from Meteor Crater!
Universe: hello Pluto take a seat and close the door behind you.
Pluto: what is this regarding to??
Universe: it's about your last day on being a planet.
I'm literally fascinated with all things astronomy and outer space etc. Just looking in the night sky on a clear night without light pollution, there's nothing like it. I just can't get enough of learning about the topic. Anybody else feel the same or similar?
I am only 11 but I’ve been begging my parents for a telescope so I could look at all the nebulas etc.
@@Markus_Andrew thanks, great information, I use to own one as a child, in my adulthood, I'm yearning for another telescope, bigtime.
@@jzblk5148 No worries, hope you can get yourself a scope soon! I changed the "pros-and-cons" link in my previous post to a different one. The page the original one pointed to appears to have changed.
The problem with the 2006 definition is that it can only be used to classify planets in OUR solar system. Now that astronomers are discovering planets in other solar systems (even estimating their sizes), they cannot tell if a planet has "cleared its orbit." Moreover, even our solar system has outlier objects within certain planetary orbits (including Earth). What does it mean to "clear its orbit" anyway?
I would prefer a definition that is much more simple:
A.) Has sufficient mass to assume a spherical shape; and,
B.) Has a radius of at least 1000 km.
In our solar system, this would include Pluto and, most likely, Eris. It would not include Ceres. However, in other solar systems, this same definition could be used -- even if we don't know the orbit of that planet around its nearest star OR if the planet itself is deemed a rogue planet.
The exoplanets we detect are rather large. Not many are smaller than Earth so we can safely assume they have cleared their orbit. If they havent, they would be too small to detect in the first place.
The universe has alot of Roaming planet, Many is bigger than Jupiter and have atmosphere, magnetic field and some have Ocean. But they don’t have a sun. so according to the scientist they are not planet? So what are they, flying rock ?
Agreed. It's a bit of a logical mess, isn't it?
@@cjshakes False. Planets the size of Earth wouldn’t be able to clear an orbit that’s 50 AU away for its host star.
Exactly! The IAU definition is idiotic and doesn’t make sense. Myself and many planetary scientists use the geophysical planet definition. It says a planet:
A) has sufficient mass to assume hydrostatic equilibrium (round) shape, but
B) has insufficient mass to undergo nuclear fusion at any time.
It’s important to add nuclear fusion to the definition so we don’t include stars as planets. By this definition, there are about 110 planets in our solar system. It also applies to all planets around all stars and even rogue planets. 👍🏻
Pluto is still a planet for me .. because this object very active geological surface, Lots of interesting discoveries like volcanoes, water ice of mountain range, thick atmosphere.. Pluto is my 2nd favorite planet after Earth ..
The first picture of the planets showing in the night sky is fascinating *. *
I bet the "Pluto is still a planet" people also think fire is still an element.
Clear cut, simple, and concise. Nicely done.
Very satisfying answer to a controversial and popular question.
Keep up the good work and all the best for future.🍀😇
I wonder if some people in the 1850s were pissed about the "demotions" of Ceres, Vesta, Juno and Pallas? Maybe there was a "Make Ceres a Planet Again" movement.
While Pluto is not technically a planet anymore, dwarf planet means we are continually discovering new things out there. I think Pluto can hold its own with the fact that it has five moons, an atmosphere of sorts, unique geology and surface features, and a crazy orbit to name a few. I’m so glad we got to see it up close with the New Horizons probe.
Either way, it should be awarded honorary planethood, so it can attend planetary reunions
Yeah
Pluto sure hasn‘t cleared its orbit. But do you remember Shoemaker-Levy-9 @ Jupiter? Or Chelyabinsk? All this happened because neither Jupiter, Mars, nor Earth have cleared their orbits! Well played, IAU.
Well they did. The astroids that go into there and our orbits were disrupted in there orbit, making them fall into the planets orbits.
those two belts used to be the sun's ring. but the planets dug a hole in the rings for themselves and now we call what's left belts.
More to the point, Neptune hasn't cleared its orbit. It has a whole class of objects called Plutinos that cross its orbit. Jupiter is harried by two swarms of asteroids in its L4 and L5 points. The IAU's definition is, as the Brits would say, pants.
@@Markle2k those objects are on a collision course with Neptune. Sure it'll take a few million years but they'll be cleared. Plus they only cross it's orbit they're not in it's orbit.
@@bg1052 No, they aren't. Like Pluto, their namesake, they are in a resonance that prevents them from approaching Neptune. Pluto actually gets closer to Uranus in its orbit than it ever gets to Neptune.
Pluto always is a planet to me. Counting juno, vespa, ceres and others yes those can be called something else like Pluto but even Pluto has more moons than Earth and Mars combined! (maybe picked up in the kuiperbelt tho). I also read a book on some genius math that somehow exactly predicts the planets distance from the sun with just one formula. It counts from mercury to pluto (going from Jupiter to Saturn directly) and even pointing out that Planet X should exist. I just see many differences between Pluto and the other small objects, making it just fitting to be a planet because it stands out of the other Kuiper belt objects.. There even is a photo by New Horizons looking like Pluto has a very thin atmosphere.
Fun Fact: Vesta and Juno wouldn't be considered as Planet's, they would be called Asteroids instead.
My boyhood interest in Astronomy began at about the age of 9, when I read a children's book called "The Search For Planet X" and learned about Clyde Tombaugh and his discovery of Pluto. I've often wondered what Tombaugh would have thought about Pluto's "demotion" to dwarf planet. Of course we'll never know, but my own feeling is that, after some initial disappointment, he would have been excited! Excited that Pluto didn't turn out to be merely another "planet", and an oddball one at that, but the first to be discovered object in a vast new category of objects in what we now know as the Kuiper Belt. Actually, Pluto sort of straddles the boundary between these two categories, and could probably be regarded as both a Kuiper Belt Object AND a Planet. How cool is that?
By the way, since Neptune hasn't cleared out it's orbit either (Pluto is still there), I'd like to know why Neptune is still considered a planet? Might makes right?
So will Pluto clear its surroundings or not? Maybe it is a future planet?
If it works really, really hard and applies itself very diligently, then maybe.
Pluto is a dwarf planet, Jupiter is a gas giant planet, Earth is a rocky planet. Earth is way more similar to Pluto than it is to Jupiter. It's fine to say that Pluto is a dwarf planet, but if you're going to use that to say that Pluto isn't a planet, it would make more sense to group Earth along with Pluto in the "Not Planets" group, than to group it with Jupiter and the gas giants.
Planet/dwarf planet. Tomayto/tomahto. I care not about any decision by the IAU- Pluto will always remain #9 to me!
Besides, only 170 something out of over 10,000 members voted for the definition, kicking #9 out.
Excellent video, as always. I was just telling my four year old about Pluto and Ceres (she has just learned about the solar system in school). This video was posted at the right time for her :)
Pluto should be proud of being the first in its category,... Great Video and thanks again.
Wouldn't that be Ceres, though?
How can anyone not like pluto! Look at its beautiful and weird colors! Its good that there are rules so that we can correctly categorise the celestial bodies! Nice video btw!
This channel is also underrated... Just like Pluto..
LOVE this channel..!❤️❤️💖💖
I would argue, that Pluto is overrated. I mean it gets waaay more attention than any other of the objects in the Kuiper Belt!
@@bjarnes.4423 c'mon, my friend, what do you prefer? A lady with good beauty and heart OR a HEARTLESS bitch.!!😆 BTW love your comment💖
Love your videos man
By the definition given there, Earth and Jupiter are not planets either as they have not cleared their orbits. I suspect that definition was created with the sole intention of excluding Pluto. After all, the orbit of Pluto is so elliptical, that by that definition Pluto must clear Neptune from its orbit as well. And even an object as large as Jupiter, in the same orbit would have difficulty "clearing" that orbit.
spacecadet35: That's right......none of the planets (except Venus & Mercury) are really planets if you accept the new definition.
It’s a mess of a definition and is functionally useless. Instead, use the geophysical planet definition.
I just discovered all of that you said on the video other day, you really made a resumed beautifully explained video, thank you for your hard time doing something that people just can't understand because it's not simplified.
I heard some scientists say, during the initial debate timeframe, that if you took the Earth and the Moon, and dropped then down where Pluto is now, that Earth would be reclassified as a minor planet, which would just be silly.
The objection I have to Pluto being reclassified is that it just seems like human arrogance and not wanting to count too high when we discuss how many planets we have (apparently we can't go past ten for some reason), so we find ways of classification that aren't really valid, just to make us happy, in a universe that has no obligation to make humans happy.
@Unknown Wasn't my logic, was several professional astronomer's logic. And of course I watched the video. Also, we now know that in the same orbit that Earth follows we have debris, so we ourselves have not cleared out our orbital path, and hence, are not a planet (based on the rules that rejects Pluto as a planet). Its a dumb rule, that needs to be revoked, and we humans have to deal with the fact that the Universe is not as orderly as we wish to have it be, but instead, adapt to the realities that are before us.
Yes, astronomers didn’t want to have “too many” planets, so they took a politically driven, emotional charged vote to change that. Some even tried to erase Tombaugh’s legacy! That’s not science. Science doesn’t work by way of convenience, something astronomers like Astrum will unfortunately never understand. The IAU made a foolish mistake and are continually laughed at. The geophysical planet definition is the way to go.
@@Jellyman1129 well here's one last words...
fuck both definitions.
It's more a reclassification than a "demotion", and it's not like Pluto has feelings anyway. I don't understand why people are so bent out of shape over it. I'm a huge fan of Pluto and I don't feel sad that it has a different label.
I don't mind it being called a Dwarf Planet, is the term transneptunian object I hate with all my heart.
Why not? First they tell us it's a planet, then they say it's not. Indigo used to be in the spectrum, now it's not. Yugoslavia used to be a country, now it's not.
They teach this stuff as if it's important, but keep changing it and making shit up.
And what about Gustav Holst and his work, The Nine Planets, a symphony for each planet, INCLUDING Pluto. Did anyone even think about poor Holst? It's not easy writing symphonies, and now he's got to call it The Eight Planets and a Dwarf. What kind of title is that for a musical work?
But no, these scientists have to go and change everything, 'cuz they just can't stand the thought that real people might understand them...
@@Morpheux1 Well, at least you are passionate about something.
You're a "fan" of Pluto? When does its next album come out?
@@DieFlabbergast Pluto is set to release its next album in just a year! Of course that's a Pluto year, so we'll all be dead by the time it comes out.... Being a die-hard fan comes with its sacrifices.
You didn’t mention how many planets haven’t cleared there path and have asteroids that orbit along their orbital trajectory, so this classification is highly disputed.
Surely while there are trojans at Lagrange points no planet has cleared its orbit and must be demoted and kicked out of the premier league immediately. So, the solar system has no planets; now what?
While Astrum makes great videos about galaxies and black holes, he always fumbles with videos about planets because he’s not an expert. His video on Ceres was a travesty and this one ain’t much better. The IAU definition doesn’t work, despite how much astrophysicists pretend it does.
At 3:08, Quaoar is listed as having "Weywot" as its moon. Sounds like some astronomers were analyzing the photos and said, "Wait, what ?" :)
hey man its hard to see a tiny Moon that is obscured by its Parent Object
@@titan-1802
I was trying to make a joke based on similarity of pronunciation. Sounds like I did not succeed...
@@Hexanitrobenzene don't worry, i've also seen the joke too.
One naturally wonders whether New Horizons would even have happened if NASA had known Pluto’s demotion was in the offing. It was probably just as deflating to the NH team to realize that the raison detre for the mission-a fly-by of the ninth planet-had been snatched from them.
That or they would not have cared for how Pluto is classified, because the scientific significance of the mission is unchanged.
For cultural and nostalgic reasons Pluto will always be a planet in my heart ❤️
Don't worry. The International Astronomical Union will be holding another vote on this in the future.
Why are people emotional about classifications?
Because they have lives with no pressure to survive as did our pre tech ancestors
Attentionwhoring for likes.
@@mogyesz9 ...What?
@Stephen Morton
I was not a demotion. It was just a change, some people just can't handle change.
You may just as well ask "Why are people emotional". We like to think that as humans we are differentiated by our superior intellect, but the truth is that while intelligence allows us to overcome the basic problems of survival and reproduction it is our emotions, our passions, which motivate and drive us. We are not just a thinking species, but a _feeling_ one, and we forget that at our peril.
People are still talking about this?
Because we can't call every odd rock out there a planet just so Pluto can keep its "title".
It wen't from the smallest, farthest and less significant planet to the biggest and most important dwarf planet. I call that a promotion.
it's like creating a League B for Pluto so that it can leave League A for good
Pluto isn't a major planet, it's a minor planet, but still a planet! Our solar system has 8 major planets, around 5 minor planets, 19 major\ round moons, 175 minor moons, billions of comets and asteroids, thousands of artificial satellites, all orbiting a single star ( the sun ).
Im wondering if a planet like Venus, Earth, Mercury or Mars would be replaced with Plutos orbit, if they would be able to clear its neighbourhood. Because if they couldnt, the definition of what a planet is, is really vague.
I mean consider, that Jupiter collected most of the mass in the solar system. So perhaps we would have lots of debris in our solar system without him.
Fun fact: NONE of the terrestrial planets could clear Pluto’s orbit. That’s why it’s a bad definition.
I've always had trouble with the idea of a planet being defined almost entirely by orbit alone. I mean a Jupiter-sized planet could be orbiting in a belt of gas giant sized objects and it wouldn't technically be a planet. What about a Jupiter sized planet orbiting perpendicular to the orbital plane of the rest of the planets? Since the planets orbit the barycenter outside our sun technically are any of our planets really planets since they orbit an area just outside of the sun? That's why I would rather have the definition of planet rely more on geologic definitions (like a differentiated interior) rather than orbit alone as orbits makes the definition of planets inconsistent. Yes orbit should play a role but not predominantly.
@0:21 Vesta and Uranus are also naked eye visible in the right conditions
No, Uranus isn't. Saturn is the farthest object we can see with our own eyes. It's why we didn't discover them till we had better telescopes.
i love Pluto the most thanks to your New Horizons series Alex. Its unique and the best looking amongst them all.
Buddy I love your videos.much appreciated.thank you
If the new "clear" definition of what a planet is would apply to all planets, that would be a good start. There is even a LOT of stuff in Jupiters orbit.
Basically they decided which are planets and then tried to engineer rules that covered that. Where for example they had to do a handbrake turn around mercury when it came to size.
5Andysalive those are Jupiter’s moons. They orbit Jupiter itself. In Pluto’s case the asteroids are not orbiting Pluto. So a dawrf planet it is.
@@NazmusLabs No, there’s thousands of asteroids in Jupiter’s orbit not orbiting Jupiter itself. So Jupiter isn’t a planet either by the IAU definition.
Exactly. It was engineered to limit the number of planets just so people could remember their names. The IAU embarrassed themselves and planetary experts unanimously ignore them, instead using the geophysical planet definition that’s much more accurate.
I love this channel. God Bless my friend!!!!!Keep up the good work....
4:17 congrats Ceres 👏👏👏👏
This channel is awesome, thank you.
Astrum, thank you for making such good content. I'm going back through your what have we found series. The context as well as the real images you show is as enthralling as it is entertaining. I'm a casual science nerd and am astounded at the amount of breathtaking imagery you have managed to introduced me to.
Cut a little off the low mid (or upper bass) in your recording eq on your voice. You have a likeable voice but this 250hz "boom" is tiring at length. Maybe a more expensive mic might fix the problem (or backing away from the mic an inch or two) - other than that; keep up the good work and interesting topics.,
Magnificent and educational, thanks.
I really love your videos! Tks!
Can you do a video on all the dwarf planets in our solar system and where they are exactly? Thanks.
I don’t care what anyone says. If it can be a planet, it can be a planet again. Planet. Planet planet planet.
Why are you people so obsessed over classifications? Who the fuck cares?
ok, time to start roasting these little shits
if your saying Pluto should be a Planet, then that means the Grasshopper should be a type of Grass
But Neptune hasn't cleared its orbit as well if Pluto's orbit crosses it.
So how is Neptune a planet?
(Thanks for the correction)
@Carl Kirchhoff, thanks, I changed it :)
Its OK :) Pluto isn't upset, it still has a heart (1:49 lower right), a BIG one, may be made of ice, but still nice!
Pluto has always & will always be a planet to me 💙
4:00 I think there wouldn't be such a dispute if they didn't _exclude_ Pluto from the planets. Why not just make "dwarf planets" a sub-category of "planets", as the name would indicate? Then Pluto, Ceres, Makemake etc. would still be planets. You could make also sub-categories such as "giant planets" (Jupiter, Saturn, Uranus, Neptune) and make Uranus and Neptune a sub-category "ice giants", as they are called anyway.
Pluto will remember this
Another problem is that Neptune can't be a planet either because, like Pluto, it hasn't cleared its orbit.
I love this channel.
Thank you, Alex! ♇
I enjoyed this video 👍👍
This is what I want to know: why is it that Ceres, Pluto and Eris are not planets yet a Bus sized rock orbiting a gas Giant is considered a Moon?
So, it basically comes down to position.
Wouldnt Mercury become a dwarf planet, while Pluto becomes a planet again if the two switched orbits?
Ice makes up an insignificant portion of Pluto, in terms of mass, right?
Also, mass doesnt matter that much, the Sun cleared Mercurys orbit, it would do the same for Pluto.
Because it supposedly doesn't clear its path of debris like a major planet is supposed to do. Which seems to be made up reasoning to me, and may even be irrelevant.
Pluto is a planet, and a powerful one at that. It maintains a satellite bigger, in relation to its own size, than The Moon is in relation to Earth. Moreover, Pluto may be unique as the only double planet system in our solar system. Pluto and Charon are actually in orbit around each other, and are tidally locked to each other. That kind of thing doesn't happen by accident.
Finally, Pluto is geologically active enough that it is far more of a vital, living plant than Uranus, Mercury, or Mars. It doesn't have the perpetually ancient, unchanging surface features we typicalky see on such dead and dying worlds.
In fact, Pluto is so active, and dynamic, that might be why it doesn't clear its path. Rather than pushing away, it pulls objects into its path.
I've always believed Pluto was responsible for the perturbations first noted in Neptune's orbit. I'll never believe otherwise.
ok if it's powerful enough then why did it became into a cloud of debris after it was shot by the Death Star
Absolutely! I couldn’t agree more! 👍🏻
Doesn't matter that it's a Dwarf Planet, my money is still on Pluto being revealed as a secret Targaryan...
Thanks for sharing!!
I have no problem with Pluto being classed as a dwarf planet, however it should be a category of planet, and not thrown in the cosmic junk drawer that is "minor planetary object". Instead what would make more sense is to have four classes of planet, Class I for ice and gas giants, Class II for terrestrial planets like Earth, Class III for larger dwarf planets like Pluto and Eris, and Class IV for smaller dwarf planets like Ceres. I think that would be fair, and that also avoids the issue of having to teach kids to memorize a bunch of planets. Class I and Class II can be called the "main planets" or "classical planets". Pluto, Ceres, Jupiter, and Earth are all very different from each other, but have far more in common with each other than with Pallas or Juno. That said, I do think large non-planetary objects like Vesta, Pallas, Juno, Chaos, and Albion deserve their own category as well (not as planets, though, maybe "sub-planetary object").
Great story: not too long and not too short! Love the channel! ❤️👍🏻👌🧐
It's a planet, and the best planet.
I still have a soft spot for little Pluto and its big heart. ❤
Pluto is always a planet no matter what.
You got that right! 👍🏻
you people are basically treating it like a Messiah or some living creature. despite it clearly having no feelings nor any Organs inside of it.
It even has a heart on it to tell us how much it loves us and we just had to go and make it a dwarf planet. #poorpluto
damn i remember when i was born in pluto but i moved to THE U.S when i was 2
I think that one of the cause is that the orbiting focus, the imaginary point where two celestial body's orbit around, in this case Pluto with it's moons, should be in Pluto, but it is outside Pluto. So Pluto and it's moons, orbit around a imaginary point in space.
Jupiter and the sun have the same situation where they orbit each other. Nobody is saying Jupiter isn’t a planet.
If Pluto is not considered an actual planet because it's a dwarf... It's like saying that Peter Dinklage ,Warwick Davis, or Verne Troyer aren't really human beings because they're not as big as everyone else! Just seems wrong to me...
your comparing a Living Organic being compared to something that isn't even sentient or alive..
*Pathetic*
Congrats on the promotion Ceres, but you gotta wait for the next one
I don't see Pluto colliding with any more asteroids than Earth or Jupiter do, that in fact means it has cleared it's path.
still sits incredibly near the Kuiper Belt, still a Dwarf Planet.
@@titan-1802 Mars seats incredibly near the Asteroid belt 🤷
If earth had formed where Pluto is, would it have cleared its orbit? If Pluto had formed where earth is, would it have cleared its orbit?
Earth wouldn’t clear Pluto’s orbit, but Pluto would clear Earth’s orbit. It’s a bad definition.
will there be another Q&A session when you reach 200k subs?
Haven't really thought about that! So mayyyybe
I would like to learn more about Dwarf Planets. Until Pluto was demoted, I had no idea that we had other Dwarf Planets in our solar system. I don't remember learning about them in school. And I love this channel. So educational.
Pluto still loves us whatever we call it, see that big heart?
Make Pluto great again.
Yo you can't say "dwarf planet" without "planet"
Your voice lowers my blood pressure.
I don't think it particularly matters whether Pluto is a planet or not but that rule about clearing the orbit is an ad hoc rule designed specifically to exclude it and the other kuiper belt objects to keep models of the solar system neat and tidy, and nothing about it reflects reality. How do you even define 'cleared'? How many objects can cross a planets orbit? of what size? There are whole groups of asteroids in Jupiter's orbit, is it a dwarf planet too? Being able to remove things from its orbit has more to do with that planets orbit than any properties of the planet itself. It's completely arbitrary.
This can be blamed on haste. As Pluto was the only "planet" to have been discovered by an American, there was a rush to declare it a planet even though it had not been studied well enough to understand it's size, mass, orbit and other characteristics. For example, Pluto's "moon" Charon (discovered decades after Pluto) does not actually orbit Pluto. Because of its mass, Charon and Pluto both orbit a barycenter in open space. They are also in mutual tidal lock, which no other planet-moon pair in our solar system are. Thus they each show the same face to each other at all times. From much of the surface of either body you cannot see the other body ever. Once the other big round things in the outer solar system started to be discovered, it became clear that Pluto was in a different category than the eight main planets.
although while Pluto had been demoted, this wasn't the only time this had happened.
(I.E. Ceres)
I have a severe anxiety disorder. Your videos always help relax me.
So would the planets of the Trappist-1 system be dwarf planets? Since they orbit their red dwarf star so close, they have not cleared their orbits. Trappist-1c is only 1.6 times farther from Trappist-1b than our moon is from Earth. Is that far enough to clear the orbital path?
I agree, it’s a terrible definition. By the fantastic geophysical planet definition, they are all planets. Even round moons are planet too.
so according to this: The Trappist-1 System of Planet's can be considered Dwarf Planet's because they orbit so close to a Red Dwarf Star that they apparently didn't clear their orbit.
to be honest, i say nobody is in the right, Pluto Lovers, IAU, all not in the right. because both definitions are dogshit either way, not even noticing the flaws within their definitions.
@@titan-1802 While o certainly agree the IAU definition is bad, what flaws does the geophysical definition have? It’s as simple as it gets.
I think Carl Sagan would disagree
Your just giving Pluto believers a platform
