Exploring the TRAPPIST-1 System
We've briefly discussed exoplanets and some methods that we can use to detect them, but we haven't yet looked at any specific ones. You may have heard of the TRAPPIST-1 system that was discovered recently, and for good reason, it's a very exciting discovery! Let's get a closer look at this system on Space Engine and see just what makes it so special.

Imagine if both Trappist-1 d and e end up habitable and develop sentient life at around the same time. How crazy would it be live on a planet where you can look into a telescope and see nightlights of an another civillisation.
The odds of that happening are astronomical but it's a cool thought nonetheless.
I see what you did there
If i lived on one of those planets i would think that life would be very common
Why not f and g
You wouldn’t even need one honestly.
I feel sad for all the flat earthers and space deniers that can't appreciate the existence of things like that in our universe.
don't. they made the choice themselves.
They are sad for you that you cannot appreciate their sky wizard and that you don't believe in heaven.
Alternate ideas should be supported
@Stiggy Vanderkskeen why would they lie? what's in it for NASA or whatever to waste millions just to hide the shape of the Earth or space?
I agree and approve this message
Can you imagine being on one of those planets and seeing another planet so close to the one you are on?
🤙🏼
I would probably faint
it would be very beautiful
Just like in the movies.
stop.
Why is it so satisfying to imagine/dream living on exoplanets? It seems so exotic and happy places.
In my head I imagine paradise on planets.
No wars, conflicts, terrorism, or anything else like that. A fresh start at a new society.

Just imagine that some where out there that a being is saying the same thing about our solar system. “This star has a planet 3rd from the sun that may have life like ours” 🤯 mind blown.
But the second planet is almost exactly like our home, Vartan III. The invasion fleet will arrive there next Tuesday. The inhabitants of the third planet may fight, but we shall exterminate them by releasing small amounts of oxygen into their atmosphere.

Indeed! In fact, you'd probably be able to see the surface of other planets with the naked eye.
Also if those planets are tidally locked you would have perpetual daytime even in the habitable zones, with the sun barely moving in the sky I guess. Must be crazy
@Stiggy Vanderkskeen Yes, telescopes can only be used with imagination.

I have been laughing my head off at the videos of you tearing flat earthers and idiots alike to shreds.
Fun fact if the earth was flat it would be at a constant incline
Hi Dave, my 5 yo son loves space related videos and he was pleasantly surprised to find your Trappist 1 video. He's hooked to it now. Thanks for your channel. I'm sure my son Shrihan is going to enjoy of your space videos. 🙏
Imagine an intelligent civilization on one of these planets and having neighbors that are REALLY close that are also intelligent. Also think of all the religions these two hypothetical species created
Yup. Imagine if our Moon (somehow) had an Earth-like atmosphere and as a result comparable biosphere... Our global Civilization as we know it would be quite different just from the moon looking differently.
jack daniels bruh à fight is coming
Brutal colonialism is my first guess tbh
_"think of all the religions these two hypothetical species created"_ - creating a religion is not intelligent. Avoiding them IS.
I have a feeling that there is no life outside of this Earth. We are the special ones.
We need more exoplanet videos from professor dave... We just do
He did a very good job. And as he stated there are a lot of exoplanets found around red dwarf stars. Do note the temp he gave. So when some idiot tells you that all stars are white. And so they do all produce the full electromagnetic spectrum they all have a color sequence Our star is a yellow star. with around a 5000 K temp. But you also need to study it on your own. To see the full story. It is an incredible field. When i was 10 i started to grind my own telescope. and in doing so got a break most kids do not get. in 1973 i met an actual cosmologist and he took me in and i got a two week stent at a 200 inch monster. After that it was my field the one i would follow the longest and actually throughout my life. And one dad would learn to regret using his words against when it came time for college. It is a JUNK SCIENCE he would not help me become a cosmologist choose something else or no college. So i chose medical science. But then in 2012 i met Miss Aller. Christine Aller 3 generation PhD in cosmology. I did not say much to her just a small comment and i described my telescope to her. Now her parents would know about this telescope and its fate. the primary was cracked during transport. taking the amount of the largest at its time telescopes from 5 to 4. Her and her family surrounded to more club president. All she could say about me was ( oh that is some new member that for some reason knows all the deep sky objects without a map ) the surrounded my family and found out why i did not become a cosmologist even though i more than qualify as one. In fact i am one. 3 different groups of cosmologist fell to the same fate. Until the president could not stand how i could stop a lecture in its tracks just by saying something It is like the last one talking about dark matter. So what did i do? mention the bullet super cluster.
@@karasprouse595 woa not that this isn't riveting.... How did this .. :/ good for you?
It's probably been so for a long time, but I've recently discovered the TRAPPIST-1 system exists within the star map of Stellaris! All 7 planets are present in the system, and TRAPPIST-1d through 1f are habitable planets of three preset climate conditions (Dry, wet and cold), which is really damn cool.
Just imagine celebrating your birthday after every four days
Imagine having months every few hours
"How old are you ?" "I'm 10000 years old"
0:19 the planets are so perfect there it looks like the Trappist-1 star has 2 little planet eyes
This makes me appreciate our planet even more... How lucky we are for all the right and comfortable conditions for our home.
Imagine celebrating a new year every week XD
Happy 700th birthday mom!

Living on a tidally-locked planet would be a cool idea for a role-playing setting
I'd play that.
Depending on the planets distance from its star and the size+brightness of the star itself it would either be interesting, or you would die instantaneously from either scorching heat or frigid cold.
Jamesthesaiyan or you would have to live on the border between day and night

I had a question while watching this. With all the orbits only taking days to complete, how frequently do all the planets at Trappist line up perfectly for an epic train eclipse of sorts? Or, if this ever happens at all? Might be a dumb question, not sure lol
I Love you Videos Sir!! You are the BEST Scientist on KZhead‼️‼️‼️
I agree!
Prof Dave don't stop explaining

This is like a civilized top 10 list.
This type of information is so exciting. Thank you for this video.
Do more on astrobiology and astrophysics, Dave! I love it!

This is so fascinating! Thanks Professor Dave
man, i love these videos! I like listening to them while world building or drawing
Please do more of these! Even if I don't have access to the latest and greatest telescopes and don't understand the math and science behind it, I always love hearing about new planets we're discovering. Also, it's super fun to go through the comments section of your videos *specifically* to look for FE-ers and denialists floundering around trying to discredit you.
Excellent, as always! I would love to see a series about exoplanets. Love your work (and I won't mention your entertaining FE vids...er...damn!)
How fascinating! I sure do hope that one day we get to visit these things. It'd be interesting to also see if they have their own complex societies. Living out lives much like we do and in their own special ways.
Thank you Professor Dave I really enjoyed this. Can you imagine the night sky as seen from one of the inner planets? I think that would be really cool.
Fun video! Love the artist rendering of the planets’ landscapes!
I'm a tourist from the past and what you have been able to discover is fascinating. No one will believe me back home. Nice moving pictures btw!
They are called the tea-there.
shut up
This system seems so flippn old , I could imagine seeing some alien ruins on these exo-planets .
Great video professor! How common is for planets to be on a binary star system? Read somewhere that that is the case for most planetary systems too
yes binaries are quite common!
@@ProfessorDaveExplains I assume the answer is yes, but do these binaries have habitable zones as well? What's the difference between what a habitable zone would and would not be for these systems compared to ours?
@@Eric_The_Cleric Seeing the professor didn't answer you... allow me. Yes, binary system have habitable zones too. There are two types of planets that could exist here. Planets that orbit both stars and planets that orbit just one of the stars. There are a lot of variables to consider when determing if a planet may be habitable or not. Too many to explain here in a comment but you can google it if you like.
@@Eric_The_Cleric en.wikipedia.org/wiki/Habitability_of_binary_star_systems
I cant believe I just found out about this channel. Gotta watch every single video. Amazing.
Good stuff Prof Dave. You have a very friendly, understandable voice and tone. 👍
Maybe it's a good idea to make an adventure game of this solar system on each planet in different chapter.
being so close to their star and thus orbiting so rapidly, wouldnt there be tremendous tidal forces at play as well? Which might heat up the planets and make them habitable beyond what would normally be the outer edge of the habitable zone?
Planet h is however too far outside .Tidal forces are good for planets e,f,g warming them up and some of them could be i 3:2 resonance
It would also depend on the atmosphere--a high greenhouse effect could quite easily let the planet retain enough heat to have liquid water. Another possibility could be that the outward side of the planet is frozen, but some or all of the "sun side" gets enough light to be habitable. And when talking about "habitable zone", bear in mind that two of the best local candidates for extra-Terran life (Enceladus and Europa) are both well outside of it in our solar system.
Tidal forces will add heat to the planets or lock them to the star (like Earth has done to the Moon). The expectation is that most or all of these planets are tidally locked, so they won’t experience any tides as a result.
been looking into this very interesting system for awhile now, and it looks very promising
I love this stuff I could watch videos like this all day long
Correction. We haven't discovered 'hundreds' of exoplanets. We have discovered THOUSANDS.
The last time I was this early, I was a Time Lord!
Dude you're awesome lol. This is like, the most interesting star system, and you had a video on it yay
i had to do a basic, lab style, report on this system a couple of months ago based off of some star brightness data, i didnt realize just how significant the system actually was
I heard Aquarius and my interest went from like 6 to 10 real quick
The TRAPPIST system looks like Earth's trial run..
Excellent video as usual
Please do a video on Kepler 1649C. It is a new exoplanet found in mid April 2020 and is the most Earth-like exoplanet found to date.
Wouldn't these things be huge in the sky if one were to stand on the surface of their sister planet? Think about what their lore and storytelling might be like if a civilized species evolved along the terminator line of one of these worlds... where this giant vicious red ball of fire loomed on the horizon ever-still... and burned and scorched the lands beneath it, with other worlds flying by like slightly smaller moons and occasionally traversing across this massive red fireball as these ethereal black orbs. Fascinating stuff.
Imagine orbiting UY-Scuti or Canis Majoris. That would be insane! The star would literally consume your entire field of view :D
Strange how whole system completes one revolution within a week 🤔
2:01 is to me such a great visualisation.
Next time I sit down with a tall glass of Chimay I will most certainly visualize the planets in the Trappist system. Excellent!
Weird. All the planets in the TRAPPIST-1 System aren't 2D circles???? The flat earth community has lied to me.
TRAPPIST-1d iS fLaT!! rEseArCh fLat 1d guys!
You're absolutely right. I mean just take a look around or something; one of the system has to be flat. It is usually the most arrogant and narcissistic one, so "d" is the obvious choice. xD

Best video about the Trappist system ! I'd like to make a more detailed animation in 3d studio
That _"Terminator Line"_ ... Somehow, it hits me hard upon a re-imagining of how that line would look on _'Kharak'_ (from that certain RTS video game, Homeworld) - just barely-colder on both North and South, and blasting heat-wave at Equator...
The good side of living in this planet is that you can celebrate your birthday every single week 😂 One earth year is like a week in those planets. Technically I am 27 in Earth but about 2457 in Trappist-d 😔
"Hotter than Venus and likely uninhabitable." So you're telling me there's a chance.....:P
What amazes me is how many planets we've found using the transit system. If the orbit of the exoplanet doesn't transit the star FROM OUR PERSPECTIVE we'd never see it. If we were directly under, or above the the orbital plane of these planets they would never transit their star from our perspective. Its amazing to me so many of them do.
Sir I love your channel so much ... You are my saviour please suggest me some books in calculus , phisics, chemistry, electronics I want more in depth learning
i imagine with such short years there’d be no such thing as seasons even with dramatic axial tilt.
But if some of them spin, the daylight cycle there is quite interesting
Well if they are tidally locked. That would mean their day is the same as their year. So speaking of years lasting a few days maximum. Even if they did have seasons then Spring would last like 12 hours (if the year is 2 days), 12 hours of summer, 12 hours of autumn and 12 hours of winter. Crazy if you think about it :)
Seasons would be called: Morning, Day, Evening, Night...
@@Shuhister Not really. Being tidally locked you either have day or night. With dusk in between.
@@SandsOfArrakis Was paper about it and 2 planets if not more can actually be n 3:2 resonance
Too bad we can't visit any of this :'( I feel like we're stuck in this part of the universe, hell, this solar system.
if only we could find a way to travel 35 light years. maby in 1000 years humans could find a way.
What I would give to see a clear-sky view while in this system. Just a rough estimation, but I think the planets would appear about as big as our moon to us at their closest approaches to each other. (Probably not as bright given the likely lower albedos and cooler thus redder star light, but still, it would look awesome!)
That theoretical habitable band at the terminator line on tidally-locked worlds would make for a fascinating science fiction setting for a novel. If I could write for sh*t, I’d get right on it. I hope someone else does.
Just look under examples->Literature at tvtropes.org/pmwiki/pmwiki.php/Main/TidallyLockedPlanet
Thank you for saying "less than half." My pet peeve would be "more than two times less."
Imagine reaching the Trappist system to find more humans. Like, literally another human race. That would really freak me out, way more than if we found life completely different to us.
Yes
It's either cat people or we glass the whole thing out of disappointment
What a great playlist of videos, thank you for bringing me closer to astronomy Dave, really appreciate your work. Best of luck!

This is an awesome solar system. I hope it gets explored more thoroughly in the nearby future.
Waiting on JWST to do in depth spectroscopy.
Excellent!
That star at 0:20 is super eager to hear some science stuff Edit: at 8:27 it closed is eyes and opened its mouth in shock at how much science stuff it learned
When will we go there ???
not in our lifetimes sadly
@@ProfessorDaveExplains yea we would need to significantly advance our technology very quickly just for the even slight possibility to plan that trip let alone leave or get there in our lifetimes.
1:11 that means nothing at all, since all stars are also made of gas, and with increasing mass they become able to hold significant amounts of plasma, or unformed matter as a protium-Neutron-Electron soup, which is mixed with infused hydrogen and helium-3. Except this star is too small for that, and hence only primarily uses the hydrogen-> helium-3 process. It would still be too small (due to being 0.089 solar masses, far under the 0.3 masses needed) for any CNO fusion to happen and too big that deuterium would be a significant factor in fusion processes, like that is in Brown Dwarfs (deuterium is the primary indicator, Hydrogen’s passive aggressive isotope cousin, and in some cases like Jupiter magnetic energy as well as meaningless amounts of deuterium fusion can give off radiation. Hence TRAPPIST-1 might be one of the smallest functioning stars we know of, and likely one of the longest lasting.
This isn't just for this video but for all the content you make thank you. I got interested first hearing you debunk flat earth idiots and then your "debate" with Kent Hovind, but the things I have learned about chemistry and the history of my own country through the presidents has greatly improved my understanding of the world I live in.

On one planets I wonder how the other planets in the system would look in the sky of the planet you are standing on.
Can you please make more of these videos?
Was there a way to determine if the planets are tidally lock?
Idk
a way to tell is to see how close the planet is to a star if it's really close to it then most likely the stars gravity will make the planet unable to rotate on its axis.
That one planet literally has one HeII side and the the other is Heaven because it's cool...👌🏼💯✔ The habitual zone is purgatory, where both demons and angles play...😬
i think 1f seems most likely for life to evolve and survive.
Fun Fact: Trappist is an order of monks that brew beer. Most trappist beers are made in Belgium and this solar system was discovered by Belgian scientists, so they named it TRAPPIST, after the telescope they have placed and used in Chile: Transiting Planets and Planetesimals Small Telescope, or TRAPPIST for short.

The system is too young for any of those planets to have oxygen atmospheres. Plus the flaring from the star probably strips the ozone column of any planet with an oxygen atmosphere, or will when they evolve. So look for microbes in the seas if there are seas present, but no metazoan life.
Barton, the question of oxygen in the atmosphere is very important, as you seem to understand. Currently, to the best of my knowledge, there are no known planets with a significant amount of oxygen in the atmosphere; since oxygen is very reactive, any oxygen that might have existed in early non-earth planetary atmospheres has long since reacted with metals to produce metal oxides, thus eliminating oxygen from the atmosphere. Photosynthetic life on earth has produced the oxygen in our atmosphere, so the lack of oxygen elsewhere strongly suggests that photosynthetic life as we know it does not exist there. I look for the day when oxygen will be discovered in the atmosphere of an exoplanet; that will certainly be one of the greatest discoveries of all time because of the strong suggestion that photosynthetic life exists on that exoplanet.
Well you don't really need oxygen for earth-like life. Sure it could still be carbon-based, bit it could have evolved to use another gas, like nitrogen or methane for example, or even carbon dioxide. Life is very flexible. Basically, life needs water, an energy source and nutrients. Sure, ozone in the atmosphere is needed to protect life from radiation, but life could have evolved to tolerate high levels of solar radiation. You just need a few individuals that are more tolerant or better adapted to higher levels of radiation. Over time you have life that's adapted to those conditions. If it's bacterial then this process can happen very quickly, possibly in just a few years.
@@sigisoltau6073 None of those gases will work as an oxidizer. Without oxygen you don't get metazoan life. Only microbes.
