Ha! Funny thing is, when I was a kid, I made up an imaginary planet, with its own map, climate, history, etc.--and it was around Rigel. ...BOY did I ever get the length of its year wrong! :P
I don't quite remember...but I do remember it was in like, the hundreds of years, NOT anywhere near the _millions_. I was like, "Well, Pluto takes like 200 years to go around the sun" (and yes, it was still the ninth planet back then!) "and Rigel is way, way bigger, so the first habitable planet would be like...maybe the fifth instead of the third? And it'd be way way further out than our Jupiter, too, so like, the year would be about...oh let's say 500 years? Yeah, that's a big difference. That'll probably be enough." I then went on to do stuff like make up a global map with alien continents, a pink sea, and a legend showing what colour meant what biome and how many miles an inch was. ...never realising that my poor civilization would probably be FLOATING IN LAVA that close in to a blue supergiant! :P (Well, I _was_ a kid, and we didn't really know any confirmed exoplanets then, and the Goldilocks/habitable zone phrase didn't exist yet. STILL!)
+Robin Chesterfield Your hypothetical planet can still exist, you just have to recreate your scenario and move it out further away from Rigel like in the video for there to be *PHYSICAL LIFE* like on Earth. Maybe it can be say, the 1000th planet from Rigel. Allegedly, there is a race of spiritual extra terrestrial beings on a planet around Rigel called the Iarghuns, and the Sirians from Sirius have a colonized planet there, and there may be a Reptoid planet there, but these beings are spiritual beings, not 3D physical beings like us. You simply do not feel hot or cold in the Spiritual Realms unless you are in Hell, and you do not have to eat, or drink anything physically, (Though you can) but rather, you absorb energy, (Any kind) as food. These extra terrestrial spiritual entities are basically angels and demons. A spiritual civilization around a Pulsar, White Dwarf, or Blue Super Giant would be very energetic due to all the energy coming from a Blue Super Giant. We would receive more energy (maybe not light, since it could be more outside the visible-light spectrum) from a blue star than from our Sun, that's insane! If R136a1 was at the distance of Proxima Centauri, we'd still be basically orbiting right next to the star, and be cooked even at the distance of 5 light years. These O type stars are very dangerous, but they usually form in groups, and star clusters together, like the Pleiades. They usually form closer to the Galactic Center too. So we do not have to worry about one of these star monsters like Eta Carinae just randomly showing up near our solar system and killing us. We are in a relatively peaceful "urban," or "country" region of space, in our galaxy and not the "big city" region of space closer to the Galactic Center.
Robin Chesterfield Well, if your planet's greenhouse effect is really small, then it could be habitable at those parts. Like, Mars would be habitable if it was where Venus is
Earth orbiting Rigel in its habitable zone, at close to 40 000 AU, you said one year would take 1,7 years... suspect you misread that, Anton. Your chart says 1,75 MILLION years. Which makes more sense. ;)
All stars you see are from the Milky Way. The closest big Galaxy to us is Andromeda. But Andromeda is still so far away that the Galaxy itself looks like a star. That is with plainly seeing with our own eyes.
The Sirius part, that's not a bug. The habitable zone is calculated from surface temperature (or, heat resonating from the star) and it's luminosity. Now... a star can be REALLY small, but have an insane amount of light and heat luminating from it... therefore, the habitable zone (though completely fictional, we would never be able to survive that far out from a star) is much further away.
He does another video about the Sirius B habitable zone though. That white dwarf is still much dimmer than Sirius A, he found that Earth had stable temperatures at around only 0.09 to 0.1 AU from Sirius B.
No the habitable zone is calculated just from the luminosity. Think about it, the reason red giant habitable zones are so far away is not necessarily because they're big, its because they produce a LOT of radiation, and so their habitable zones must be further away. The amount of radiation that Sirius B produces is actually quite pathetic, its WAY less than even the sun. Sirius B's habitable zone is much closer than 1 AU.
White dwarfs are superhot so I would expect their habitable zones to be far out. Regardless, you should actually pay attention to where the temperatures of the Earth stabilizes at 16 degrees Centigrade, because as you were talking about R136a1 saying "where liquid water can exist" Earth's surface temperature was plummeting rapidly below -110 degrees Centigrade. You should pay more attention.
so if a year was 8 days long ,would there be 2 cold days, 2 hot days and 4 moderate days. that would certainly be weird. also you would have your birthday every week
I actually did a spit take at the 5 light year habitable zone. That's like... if the Sun were that star it would make Alpha Centauri habitable. Granted given the lifespan of such a star any planet around it or near by wouldn't really have the time to become habitable for life before it went boom killing absolutely everything nearby.
G4mer 4ddict that would be awesome Merry Christmas guys 8 days later Merry Christmas guys a year later (voice breaking) Merry Christmas guys ugh I'm getting tired of this
Here's another thing to consider: blue stars only last for a few million years, so habitable planets in those systems may have no time to develop and red stars' habitable zones may be so close to their parent stars, the only way for those planets to be habitable is for them to be tidally locked to their parent stars, which, at best, would make it very uncomfortable to live there.
The weather on earth, when orbiting other stars larger than our sun, would be a lot more extreme because we’d be spending more time in each season and therefore the temperatures would be more extreme near the end of each season.
Sorry if this is a dumb question, but what are the chances that materials/chemicals arrived on Earth from Venus via a asteroid or meteor strike. Second question: Is the gravity of Jupiter and other planets in our system required to help earth stay in the habitable zone?
When it comes to habitable zones are the star's spectral profile and solar winds taken into account? For example, if Earth were put in Sirius A's habitable zone, would the intense UV radiation be too much for Earth's atmosphere to maintain itself? Would Earth's magnetic field be strong enough to withstand the solar winds?
Funny thing is, if a planet orbited in the habitable zone of R136a1, the massive wolf-rayet star would go supernova and live its entire life before the planet even made one full orbit around it.
R36A1 could dominate temperature determinations for planets in other neighboring star systems! No sense in thinking about life coming about that way because this star is probably super short lived and in cosmic/geologic time it’s about to have a collosal supernova that would wipe out any life and then cool down any temperate worlds.
5 light years? 5 lys is around 316,205 AUs, so when we apply the inverse square law, R136a1 would have to emit nearly 100 billion times the energy of our own sun. Its brightness at the distance of the nearest star to Earth, Proxima Centauri (just over a parsec), would be about the same as the full Moon (Wikipedia). So, although it's a mind boggling powerful star, I believe that the habitable zone would be much closer.
How do I explain in my fantasy noval a purple sky and a blue star? Also what would the plant life and water look like? This is if a habitable zone was around the star.
I think it might have been a bug. Because the distance to the habitable zone has really nothing to do with temperature, but just the luminosity. Rigel and betelgeuse both have about the same luminosity and so their habitable zone must be at a similar distance.
How would the seasons behave in short orbits and long orbits? Would the 11 day year have pretty level temperatures without a great deal of seasonal changes, while the 40 year “year” would have ten years of each?
The biggest problem with a long orbital period would be variable seasons. If a habitable planet could be found around one of these massive stars, there really would only be one season during anyone's lifetime, and likely the lifetime of any living organism. The tilt of the planet, any moon(s), and rotation would clearly be a major factor for life on the theoretical planet, but for diversity to develop, there needs to be variable seasons.
I don't know if it's a bug game or something but when you placed the Earth orbiting R136a1, Earth started freezing; but actually it seems that it's placed on the habitable zone, what has happened there, maybe a bug?
Yes, as most stars are red dwarves. Over 90% of the stars in our galaxy are red dwarves and their mass is usually between between 0.08 and 0.6 solar masses and their luminosities can be just 1/10000th of that of the sun
"90% in the galaxy are small warm red stars." So yeah let's get in there on a planet close, nice and cozy to melt us some ice and grow some life there. . Oh no Except for when the nasty red punk star blasts-off a really sterilizing frequency photon flare at us once or twice a year when it burps at our party. " No thanks, I won't grow-up near that red star", said Superman.
@@prasunpahari Yeah you know what? I was actually wondering why he forgot to let eartb orbit Proxima B? Oh how about earth orbiting A Star called Barnard's star,and perhaps Aldebran along with Vega?
According to some theories, the Earth is outside the habitable zone (in the hot zone) except for life keeping the planet suitable by sequestering carbon. If the Earth were to be sterilized as a runaway greenhouse effect would take place.
I don’t think so, you could have a pair of stars /planets that orbit each other and form an 8 but i think it would stabilise orbit or not last very long at all or even end up spitting each other away for good.
red dwarfs are cold compared to main sequence stars and have more flare activity in UV light and radiate infrared light so it be red shift light so red dwarfs have very narrow habital zone which greatly reduces odds of life developing.
Gravity doesn’t care how far away you are it will still manipulate earth and keep earth in orbit around R136a1 from 10 billion light years away . Yeah it won’t be in habitable zone, but is there anyway earth could safely orbit and keep life while in orbit of that star?
Probably orbiting R136a1 I would have thought would produce the longest year as it is so super powerful (8 megasuns) that you would need about the square root of 8 million or 2830 astronomical units of distance between it, which counteracts its mass of 300 or so suns. I am curious as to why the habitable zones are so much further away than what I predicted from an inverse square law. With the inverse square law 1 sun for 1 AU to make the planet like earth. A star with the power of 4 suns should be orbited from 2 AU. A star with the power of 100 suns from 10 AU. 5 light years is what you'd expect for something (probably a quasar) with the luminosity of 100,000,000,000 suns. Or 125,000 of the R136a1 star. Am I missing something with the calculations?
It's ludicrous to think that life on earth could survive for long if all four seasons were experienced in just a few days were we to have a red dwarf star. The weather patters would be so chaotic, plant life cycles simply could not be sustained.
Sirius B is a blue star which are some of the hottest objects in the universe there are no white dwarves yet but if they did exist they would be the hottest objects in the universe Imagine if neutron stars still existed all the way to white dwarf time that would be a sight to see for late astronauts
4:36 White/bluish starts are hotter than reddish stars. The habitable zone is calculated by temperature, so even if the star is small, it's going to be at quite a distance. In several of your videos you seem to not know things.
Orbiting the largest known star, in the habitable zone five light years away, that too is infeasible since the earth's orbit could so easily be disrupted by nearby stellar bodies.
how come I'm universe sandbox 2 when I tried this with uy scuti and some other more average sized stars earth didn't orbit it, it just crashed straight into it. if anyone knows why let me know.
How about putting Earth in an orbit around Pollux,Aldebaran,Vega? Will you please simulate like you did in this video putting Earth in orbits around the stars I just now mentioned in the beginning of this sentence? Again,put Earth in orbits around Pollux,Aldebaran,and Vega,ok?
...I feel like Anton is running out of ideas I don't mean that offensively, but a lot of your recent videos have been very large topics or hypothesis about topics. Perhaps I could bombard you with some old ideas you use to do but not anymore or ideas Iv come up with Your interstellar series Your KSP math (But I think Scott Manley has captured that flag) L-points What kind of planet will you need to different coloured lifeforms Just some ideas :D
Think about how seasons would work on some of these planets. Our current method of generating seasons wouldn't be valid anymore. Something else would have to be going on.
I know why the habitable zone for the white dwarfs are far away. Because they're really hot in the beginning of their lives and by beginning I mean after a sun explodes and all thats left is a tiny yet hot white dwarf.
Since everyone is talking about space and such...I wanted to bring this up but people have been saying that planets such as Venus and Neptune are losing their colors and that the sun is also turning white... Does anyone have an idea as to what could be causing a sudden change like that?
Red Dragon rumors. the sun part is true. because the sun is getting older it is becoming brighter (it has to do with novas and I could type a 10 page essay on this) pretty much the atoms are moving so rapidly from the heat their fusing which makes the sun bigger and brighter but it makes the mass smaller (eventually causing a nova)
Oh okay. I was looking into things and people were also saying that earth is over due for a pole shift as well. I also thought the sun would take another billion years for it to go into a transition...
Young white dwarves, being so tiny, are almost offensively because they lack surface area to radiate light from. This isn't actually a bug, it's just because Sirius B is a "young" white dwarf. They have to cool off.
5 light years away from a host star, now thats truly massive.

666,666,666,666,666,666,666,666,666,666,666,666 luminosity hipernovas
last time I was this early *insert astronomy joke here*
Canadian Jesus XD
Pluto was still a planet.
Canadian Jesus 3c 273 wasnt a quasar
Canadian Jesus your face cause a star went supernova
Canadian Jesus the universe wasn't even born yet
how would you even calculate age in those long orbital period scenerios?
What's your intro music
I tried doing this with other stars.. It would not show me the habitable zone of other stars other than the sun
It's ludicrous to think that life on earth could survive for long if all four seasons were experienced in just a few days were we to have a red dwarf star. The weather patters would be so chaotic, plant life cycles simply could not be sustained.
MusicInspire if we have to tech to get and colonize another planet we probably can make artificial energy
2:52 Betelguse is a Supergiant
i feel like we dont detect planets for larger brighter stars because they are too small to create a dimming
Sirius B is a blue star which are some of the hottest objects in the universe there are no white dwarves yet but if they did exist they would be the hottest objects in the universe
Imagine if neutron stars still existed all the way to white dwarf time that would be a sight to see for late astronauts
Love your content
the orbital period when orbiting rigel is over a million years, you didn't notice the M
So, if Alpha Centauri was replaced with R13a1, we would be screwed?
Próxima Centauri is closer so don't pick it. And yes we would perish
4:36 White/bluish starts are hotter than reddish stars. The habitable zone is calculated by temperature, so even if the star is small, it's going to be at quite a distance.
In several of your videos you seem to not know things.
It said 1.74 M Years which means an orbit around Rigel is about 1,740,000 yeas
Rigel earth is 39k au away and 1 year is 1.7 years how does that make sense?
The orbit for Rigel was 1.74 Million Years but still a great a video
Orbiting the largest known star, in the habitable zone five light years away, that too is infeasible since the earth's orbit could so easily be disrupted by nearby stellar bodies.
how come I'm universe sandbox 2 when I tried this with uy scuti and some other more average sized stars earth didn't orbit it, it just crashed straight into it. if anyone knows why let me know.
Aidan Richter Because you don't have it set to orbit?
10 million years? Wow!! That’s one long orbit
How about putting Earth in an orbit around Pollux,Aldebaran,Vega? Will you please simulate like you did in this video putting Earth in orbits around the stars I just now mentioned in the beginning of this sentence? Again,put Earth in orbits around Pollux,Aldebaran,and Vega,ok?
Carla Head You can just purchase Universe Sandbox
Here's another idea. Earth in a polar orbit while the other planets are in an equatorial orbit.
red dwarf makes a lot of radiation, you think its a good place to find a new home? Great content, keep it up!
...I feel like Anton is running out of ideas
I don't mean that offensively, but a lot of your recent videos have been very large topics or hypothesis about topics. Perhaps I could bombard you with some old ideas you use to do but not anymore or ideas Iv come up with
Your interstellar series
Your KSP math (But I think Scott Manley has captured that flag)
L-points
What kind of planet will you need to different coloured lifeforms
Just some ideas :D
Sirius B More like Are you Serious B?
i think datz correct 2
Think about how seasons would work on some of these planets. Our current method of generating seasons wouldn't be valid anymore. Something else would have to be going on.
Wow, I thought that the more massive the star, the faster the earth would orbit. I learned something new
Sun:I Make Solar Flares Everyday
Earth:No Thank You.
Why do you pronounce UY Scuti as UY Scut I and not UY Scutee
5:34 no it's 1.75 M years (M meaning Mega)
There's also the problem of solar winds from other stars, Earth's atmosphere could be blown away quite easily.
Name game?
How to enable the habitable zone?
I know why the habitable zone for the white dwarfs are far away. Because they're really hot in the beginning of their lives and by beginning I mean after a sun explodes and all thats left is a tiny yet hot white dwarf.
How much mass more mass does UY scuti need to go supernova?
Since everyone is talking about space and such...I wanted to bring this up but people have been saying that planets such as Venus and Neptune are losing their colors and that the sun is also turning white... Does anyone have an idea as to what could be causing a sudden change like that?
Red Dragon mr clean is bleaching their colors off
Red Dragon rumors. the sun part is true. because the sun is getting older it is becoming brighter (it has to do with novas and I could type a 10 page essay on this) pretty much the atoms are moving so rapidly from the heat their fusing which makes the sun bigger and brighter but it makes the mass smaller (eventually causing a nova)
Oh okay. I was looking into things and people were also saying that earth is over due for a pole shift as well. I also thought the sun would take another billion years for it to go into a transition...
Red Dragon it will take 4 billion years to finally happen but it doesn't happen at once
I'll never stop smiling at the way he says very
8:20 I knew u was going to say tht star
i think pistol star which is just rigel but bigger will have larger zone if not largesta
Young white dwarves, being so tiny, are almost offensively because they lack surface area to radiate light from. This isn't actually a bug, it's just because Sirius B is a "young" white dwarf. They have to cool off.
Show how many planets you can accommodate into the habitable zone of the last star R1..something.
Your Sirius B bug might be caused by the removal of Sirius A. Maybe the habitable zone calculation was not refreshed.
10 million years?
This is why we gotta work out some GST (galactic standard time) right now, before we start colonizing other worlds!
