NASA has a model for the exoplanets humanity has discovered (eyes on exoplanets), and some of them (like TRAPPIST-1 or Poltergeist, without the other planets) have custom-made models specifically for them. most of them can be found in the travel bureau

[@Trolligi]

I used to always browse that lol icl I’ve switched to Celestia and SpaceEngine, they’re a lot better. Plus in Celestia you can add custom textures to any planet (and star or other body) as well as write very rudimentary code (several lines, 30 tops) to add planets and stars and other bodies

Video suggestions for you: - The benefits (or disadvantages) of colonizing Mercury - Interesting facts about the moon Io (which imo is the most interesting among the Jupiter moons) - The likelihood (or lack thereof) of life in Enceladus, Europa, or Titan - Exoplanets that exhibit the biggest chances of holding extraterrestrial life

[@KennyG_420]

👍👍👍

[@noobscoopsies1100]

The disadvantage is probably hella expensive and very unstable since how small and close it was to the sun...

Why colonize Mercury if you can just disassemble it for ressources?

I really enjoyed this in-depth look of the Trappist 1 system. I enjoy creating fantasy worlds and I used this system as inspiration, specifically Trappist 1 - F. It's interesting to me imagining how civilizations would build up in a tidally locked planet and imagining the habitable areas influencing politics. Also having the planet so close and visible is fun. The myths they would create based off of these other planets and the calendar systems. Obviously disbelief needs to be suspended because the plane isn't actually habitable, but it really is just such a fun system.

I really like your approach that all planets are interesting even without life, your videos are super fun to watch! I have an interesting request, can you show how you use space engine? Your visuals always look great but I can't seem to reproduce them on my own. I would also be curious to see how you create these systems and planets.

[@ImaCatLovet]

[@xyrom485]

[@Gort-zs5ph]

Great show. I often wonder if these small dwarf stars get the magnetic bubble type protection from cosmic rays like our sun. Something that should be studied. If you have a distant super-nova, etc. these worlds may get hammered.

[@samiahasham1986]

Please make a grand tour of 55 Cancri star system

[@B0BBY-303]

Even if TRAPPIST-1 was somehow habitable for us, I'd still turn tail and bolt the second I'd get a whiff of just how dim the parent star actually is. I like my luminous CRI 1.0 stars from the F/G/K classes thank you very much. That fictional space tourism poster NASA made still looks pretty cool though. Still, people need to read the actual studies and research articles on these star systems more often, if they did the majority of the hype around this system regarding habitability and whatnot would have quickly fizzled out.

[@Jay-gf8tm]

Well said 🍻

[@peterpayne2219]

Cool video, the only suggestion I would make is, perhaps you should occasionally flash a subtitle indicating that a planetary panorama you’re showing us is computer generated, since obviously we’re not getting color as if we were these extra planets

[@Jay-gf8tm]

He should probably just fly a spacecraft to the actual planets he's talking about. He could record them in 4K HD so we know the exact colors they really are.

[@MukiBlalock]

Good 👍 job dude!😂😂😂🎉❤

[@redcoat4348]

While I am aware that there is a study suggesting that Trappist-1c has an atmosphere, I think this is not the scientific consensus, I feel like it's wishful thinking to expect exo-earths around red dwarf stars to have atmospheres.

[@Kyplanet893]

according to this study c having an atmosphere actually fits the data best: ui.adsabs.harvard.edu/abs/2023NatAs...7.1011M/abstract

[@redcoat4348]

@@Kyplanet893 Ahh interesting study, I was looking for what study you were trying to base your claim off of but I couldn't find it. Thanks for the link, I'll give it a read.

[@nalasprincessworld4670]

it's not likely that there's a asteroid/dust belt around trappist-1 as the gravity of either planet will pull the belt out of orbit unless it's in some sort of area where it's pulled perfectly but unlikely

[@nalasprincessworld4670]

Also if even the chance is thin as a atom that there's life on trappist-1 it will be some sort of bacteria or small fungi

[@bryanbryan2968]

I like the point you made about the ESI. Considering that a tidally locked planet denser, but smaller than Earth, at the outer edge of the HZ would have a low ESI, then it may be a better planet than Earth . . . at least the star facing side and always from the inevitable giant central bullseye hurricane.

[@TheNoiseySpectator]

What a shame. They are all do close to being inhabitable by Earth life, but none of them are quite suitable.

[@Nomad-sw4uy]

@bryanbryan2968 Better planet than Earth? Earth, as in the only known planet to have spawned animate, living matter which is perfectly adapted to the conditions it hosts? You've got some strange metrics, friend. The grass is always greener, much?

[@bryanbryan2968]

Of course, it could be better for an other species. There is a lot of things that could be said. Probably not Trappist 1f. I think we are spoiled into believing our planet is the best. Somewhat like how people favor a home sports team. But assuming you wanted a constant temperature to live in, pick a place on a non-flare dwarf star’s planet and some people would be happy. Life may not develop there as easy, because you have half of a planet to do it on. I estimated there statistically should be about 6 planets(non terraformed) planets within 10 light years from here and hundreds within 1000 light years. Your point is well taken, though, as of now, we do not have a better place to live. I also found it curious that Earth tilts at about a 23 degree angle. I am not a theist, but that almost looks engineered.

[@priestgoober5160]

Very interesting, whats your opinion on the misinformation spreading about proxima b? Ive seen so many clickbait videos saying that nasa has directly imaged the planet. Which is extremely difficult with modern technology from my understanding, and would only show a faint dot.

[@Kyplanet893]

i’m gonna make a video about it

[@kolbyking2315]

I'll give a very bad estimation with my amateur knowledge. If you image Promixa B at a 45° phase angle (for the best brightness/separation ratio), that's a 0.026 arcsecond separation. I'll assume it has an earth-like composition. That gives a radius of 1.036x earth's, a solar flux of 0.664x earth's, and geometric albedo of 0.434. That gives a 0° phase brightness of ~31% of Earth's flux. Assuming a phase curve halfway between Mercury and Venus, the brightness at 45° would be ~15% of Earth's flux at 0°. If Earth's flux is 1.74 × 10¹⁷ watts, Proxima B's brightness at 45° would be ~2.6 × 10¹⁶ watts. Proxima Centari luminosity is 6 × 10²³ watts, of which 1.5 × 10²³ is pointed towards us. With this, I find a contrast ratio of ~ 6,000,000 to 1, with a 0.026" separation. JWST's NIRCam can do 11,000 to 1 at 0.55". NGRST's CGI is planned to do 200,000,000 to 1 at 0.15". HWO capabilities aren't fully planned yet, but it'll probably need 10,000,000,000 to 1 at 0.1" to accomplish its goals. TLDR: JWST can't directly image Promixa B. NGRST (2027) and HWO(2040s) might be able to do it. An amateur's attempt at astronomy.

[@starsofaheartattack6286]

Proxima b is still a very awsome place.

[@entity_unknown_]

Would the light from such a dim star really illuminate and reveal their' atmospheres fully in the visible spectrum??

[@Kyplanet893]

not in the visible spectrum but we don’t need it to be visible light, there are other wavelengths it emits more that are good enough

[@Thundernugget]

Very cool. Thank you. GLIESIE 581 next please.

[@Kyplanet893]

[@vegassims7]

It's so weird to think such a LOW mass star still had so much dust, rock, and metal around it to form SEVEN large terrestrial earth-type worlds. How is that even possible. I could understand this if it was a yellow dwarf star like Sol, but it's not.

[@Kyplanet893]

stars form with more material than you’d think the sun had more than enough material to form several jupiter-sized planets, and honestly probably another star trappist-1 probably has less planets than we’d expect tbh

[@sulfur1661]

[@DivisionPrecision]

can anyone confirm 1b is bigger than 1g? someone said that its bigger cuz it has more mass. but im pretty sure more radius means bigger.

[@Kyplanet893]

more mass means bigger and more radius means bigger both mean bigger, just bigger in different ways (mass means heavier, radius means wider) whenever i say bigger i almost always mean mass, because finding out the radius of a planet is much more difficult than finding the mass

@tetraxis3011 Somewhat misinfo on the Mars thing-- in short, yes, theoretical, but functional.... We've got theoretical ideas, but what's that they say about the best laid plans of mice and men? Without any practical tests, we just can't know what we don't know. There are so many factors involved in a planet's climate... And those are the ones we actually know about. However... I'm of the opinion something doesn't have to be useful to humans be beautiful and interesting, no? I'd love to see what these places look like in real life.

we’re only seeing trappist-1 as it was 40 years ago, that’s not long enough for any significant changes to have occurred what we’re seeing is very close to how they look in the present

[@Two-Toned_Iapetus]

Trappist-1 system is 40 light years away from Earth, meaning that the observations we saw was 40 years ago. It is correct that huge astronomical distances can allow us to see from the past because the speed of light takes time to reach us but unfortunately, atmospheres can't naturally build up under a century.

because you usually have to observe the planets several times which takes weeks on its own then you have to check the data, get it reviewed by others, and there’s a whole thing about studies being embargoed so the people publishing them can do their own experiments and such with it before others can plus jwst also just gives a lot of data so there’s a lot to look through before you can even get the results

Trappist-1, a red dwarf star engulfed in the darkness of the vast universe, casts a shadow over a distinctive and captivating planetary system. With a modest mass only 9% that of the Sun and a radius just slightly larger than Jupiter, Trappist-1 appears to highlight a story of deep space pioneering. The seven planets of this system are all located within a surprisingly close distance from the parent star, when the distance between them is only a few million kilometers, all together narrower than the distance from Mercury to the Sun in the system. Our Sun. The proximity and special position of the planets to their host star provides a very special environment for scientific research, by opening up the possibility of alien life or at least the possibility of alien life. provides deeper insight into the formation and evolution of planetary systems.
