A Grand Tour of TRAPPIST-1

TRAPPIST-1 is one of the most interesting exoplanetary systems in the Milky Way. But when talking about TRAPPIST-1. people usually only ask if TRAPPIST-1 could have life. But what is TRAPPIST-1? What are the planets in the system, like TRAPPIST-1e, like?
This is part 2 of my Grand Tour series, where I explore exoplanetary systems in more depth.

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

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

Youd be surprised how rare an actually grounded video on anything space is. Great job producing an interesting, concise and informational video. Keep it up!

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.

Thank you for the most comprehensive description, at a non-technical level, of the Trappist-1 system that I have seen. It is indeed a fascinating planetary system.

[LorreKeeper]

I love this to no end!

PSR B1257+12, aka "Lich", is a cool system that might be worth taking the tour of! For one, it was the very first planetary system discovered around a pulsar, and two, it was the very first planetary system discovered... ever! :D

Trappist-1 is my pooki bear 🥰🥰🥰

Edit: we broke up. I’m now in an open relationship with TOI 700d, looking for any hycean worlds nearby, iykwim.

[Faulheit]

this one takes the cake for coolest sounding name

[magnetospin]

I realized there's still a lot of unknown and uncertainties, but a Grand Tour of the Tabby's Star would be interesting.

[Extrema]

TRAPPIST-1c is more interesting than what I thought, cool
About suggestions for the grand tour series, some would be:
- Copernicus
- Titawin
- Lich
- Ran

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]

bro I actually just found one of your videos randomly and I just wanna watch more!

[samiahasham]

Please make a grand tour of 55 Cancri star system

[xyrom]

Love the way you talk about what we actually know!

[Gort-zsph]

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.

[BBBY-]

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.

[peterpayne]

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

[redcoat]

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.

[entity_unknown_]

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

[priestgoober]

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.
