@Zuwaria Sarafine you’re ignoring how this planet might be very far away and hard to contact, and there’s also the problem of ethics, as a lot of people aren’t going to want to leave the rest of humanity. Plus, there’s no way children are going to be sent there, as they would be leaving their parents.

[@30gaming83]

One interesting thing about the Trappist system (as far as I understand it) is the potential impact of how close the planets' orbits around their star are too each other. Because of this, they likely play on each other's rotations, which may not only produce tides, but also cause them to *not* always be tidally locked, both of which could increase their chances of being habitable.

[@samr.england613]

You have no idea of what you're talking about, do you?

[@sciencecompliance235]

I'm not sure that would be the case. The Galilean moons all orbit relatively close to Jupiter and each other and are all tidally locked to Jupiter. Io, Europa, and Ganymede are in orbital resonance with one another, though, so these planets may also be, too.

[@huzzzer6083]

I'm just imagining standing on one of those planets in the system. Every other planet would be as big as the Moon in the sky because of how close they are to each other. That is extremely cool.

There has to be life out there. Billions of stars in billions of galaxies. Has to be a another habitable world like Earth. Guess the search continues. Or else, the Fermi Paradox is true.

[@Nebo8ful]

there must be one, but everything is so far away i doubt we will even reach one

[@kai6179]

I guess no one is crazy enough to thinks about another galaxy. But argument sake, in endless universe there are infinite number of exact copies of Earth with all us on them including.

[@JakeSpeed1000]

I don't think the question is if another habitable planet exists. Even if our speed of travel increased exponentially, getting there is unlikely before we become extinct.

[@TheHighJester9991]

the real questions how common are they and if well be able to find them before expansion hides them forever.

[@Skylancer727]

Well yes, it has to be out there, but when we make it that broad, it could be the nearest being 3 galaxies over, in which case we would never meet. From everything I see, it seems if there is life at most there are probably somewhere between 3-10 habitable planets in the entire galaxy as most places in the galaxy are totally destructive for sustainability and others are to sparse in heavy elements. We actually have one of the rarest types of stars, we happen to be in one of the less active areas of the galaxy yet occasionally pass through the spirals for extra heavy elements, and we needed a metal rich star in the first place. So with everything we know, we can rule out life in the center of the galaxy, in star clusters, and any stars of low metallicity. With that we still have a decent amount of the galaxy left though still a large portion of the galaxy are in star clusters which are far too chaotic to be stable. They also need to be in fairly spacious areas as to be far away from super novas, gamma ray bursts from neutron stars, neutron star pairs, and white dwarves. But most importantly, they can't be the stars outside the galaxy or at the very edge as we do still need some heavy elements for life (phosphorus is needed in all life and is one of the more rare elements in the universe). A lot of people also get caught up in these claims of "life not as we know it" though the elements are identical across the universe so we can kinda assume life must be as we know it as there are only so many strange ways elements can combine and for a majority we are made of the most common elements in the universe. Only exception being phosphorus which is the backbone for DNA. However, considering phosphorus is inherently rare even on Earth, we can tell there probably isn't a more suitable replacement.

Quick correction: Exoplanets letter names are assigned based on their order of discovery. Sometimes that works out to be the same as order from the star (such as Kepler-62), but sometimes not (such as HD 219134).

[@EvilParagon4]

So in reference to a comment above asking what Earth is, it would not be Sol 1-D, but Sol 1-A. Since I'm pretty sure we discovered Earth before the other planets lol.

[@mackrethreinhold5253]

@@EvilParagon4 I am not sure which comment you are referring to, but this sounds like fun little rabbit hole to explore! If we want to classify our own solar system according to exoplanet naming conventions, it would likely be Sol b, Sol c, Sol g, Sol d, Sol e, Sol f, Sol h, Sol i. Here is my justification for this naming scheme: Planets are named with *Star name* and then a lower case letter. Upper case letters are reserved for stars, if the system has multiple. Planet naming always starts with "b", because "a" is assumed to be the star they orbit. The term "planet" comes from the Greek "wanderer", meaning Earth was not recognized as a planet until recent times. Mercury to Saturn where all known since antiquity, so I guess they were all discovered together In that case, their names would likely follow their order from the sun (the sun's name being "Sol"). In that case, Earth was "discovered" after that, followed up by Uranus and Neptune.

[@marshallbradshaw3817]

@山モﾑ丂モﾚ Letter names are assigned based on their order of discovery. Earth is probably the only planet that was or will ever be discovered BEFORE its star (especially if you don't count the Sun as being discovered until heliocentrism taught us what we were dealing with, but inarguably the first human knew that they stood on something before they knew that something shone down on them). Thus Sol 1-A. ...Or maybe even Terra 1-A, since the name being the star in all other circumstances could just as well mean that the name should be whatever was discovered first, and thus the star in all cases other than ours.

[@shoam2103]

27:30 yes! It's better for me to split a long video in 2. Really enjoyed it. Especially loved the visuals and detail for each planet. I can now easily imagine how each habitable planet is unique and similar to each other. Tidally locked, position in habitable zone, color and size of star, terrestrial vs marine and mixed. Also density and composition (so water isn't uncommon?). Plus how a (not too) large planet is beneficial; with a molten core providing a magnetic shield, plate tectonics and volcanic outgassing contributing to the atmosphere. Part 2 could be great, but now that you've already covered the best (trappist and teagarden), is there more interesting content?

[@jasonreed7522]

If you disregard the habitable requirement/ideal then there are some very strange exoplanets out there. For instance "Hot Jupiters" which are gas giants orbiting far closer than Mercury does. Or i believe there is an exoplanet that is basically a giant diamond because it was originally a star but a different star ripped away its atmosphere leaving just the giant jewel. (Note that it is covered in dust and junk so it is not a shiny diamond but looks more like any other rock). That very short list also leaves off so many theoretical planets like rouge planets (planets without a host star), or interesting hosts like neutron stars or black holes, even if such an object would be short lived or highly improbable.

[@Prof.Megamind.thinks.about.it.]

Planet people , One hidden possibility her is that the cores of red-dwarf planets may be smaller than if they were yellow-dwarf planets . If true , this could be due to differential- stripping of magnetic/paramagnetic materials from the protostellar-disks . The above would greatly reduce the amount of heat put into these planets interiors , but this would typically be counter-balanced by tidal-heating . The effect of this difference upon convective -cells and plate-tectonics is unknown . The above , along with slow planetary-rotation , is likely to greatly reduce or eliminate any planetary magnetic-field . The compensatory effects might be a strong induced magnetic-field , and a very dense ionosphere . The above two effects could act together to mitigate the atmospheric-stripping effect of the host red-dwarf star . This could be considered the exoplanet equivalent of the thermal Leidenfrost Effect . The implication of the above is that even extreme solar-wind pressure and events , do not necessarily result in the removal of a red-dwarf exoplanet's atmosphere . Planets such as Trappist-1d have a very good chance of possessing significant atmospheres , possibly containing large amounts of "fossil" oxygen , liberated from water-vapor by photolysis . *.Support provided below .

Note that a lot of people seem to over estimate how red red dwarfs are. They actually vary from nearly all inferred to basically identical to an incandescent light bulb. Though personally I still say life probably is just as uncommon as it appears to be.

[@metametodo]

In visible light however they'd still be red, wouldn't they? Maybe dimmer depending on the relative amount of energy being output in infrared, but for visible light illustrations red would be the main color.

[@WanderTheNomad]

I've heard that red light of a certain wavelength and amplitude is actually good for our bodies.

[@ianmeade7441]

@@metametodo no, you underestimate how bright they are. From a distance, they appear dim and red, but they're still stars. They'd still be extremely bright to look at from an orbiting planet, so you wouldn't be able to discern any red color. That majority of red light would just contribute to the dimmer environment, which would have the light levels of a cloudy day.

[@metametodo]

@@ianmeade7441 At first I understood that OP meant that they weren't all red, but other colors as well. That's what I was trying to grasp on, but now I figure they're talking about estimating their tonality and intensity. But I see what you mean. If I'm no wrong, I believe our Sun also looks white from space. I think this debate on a star being red or yellow doesn't consider literal eyeball observation from close, but the peak wavelenghts the star emits. Because if you consider all wavelenghts of light emitted it will end up aggregating into something close to white light to the unaided eye.

[@ianmeade7441]

@@metametodo yeah, that sounds exactly right! I think the imagery of red skies on worlds orbiting red dwarfs comes the fact that most of the ones we've found are tidally locked. For the habitable regions, the sky would actually be a permanent sunset red. But for planets that rotate normally, it's like you said. Our eyes wouldn't notice the mostly red spectrum in the aggregate sunlight

[@mino1205]

You sadly completly forgot to say something about the fact, that litle Stars(Stars that are smaller than the sun) sterelize all there Planets from Time to Time. This is caused by solar flairs (very strong solar winds) This means that we could live on them but wouldnt be able to live and grow plants on the surface. It also means that live wouldt never develop on it. We would need to do everything underground. Otherwise as always great Video.

[@Tuupertunut]

I think he mentioned it at 19:11 with Proxima Centauri.

[@Ad_Astraz]

He did mention that Proxima Centauri had some very strong solar winds, that's why it's called a Flarestar after all. I don't think the other star systems mentioned in this video have solar flares on the scale of Proxima Centauri, and if they did he would certainly mention it.

[@GlaceonStudios]

@@doomi4055 Depends on the discovery order. Would aliens first discover Jupiter and Saturn, or Venus and Earth? I'd be more inclined to say Venus and Earth first, considering closer planets tend to be discovered first. Possibly Venus would be Sol-1b and Earth Sol-1c, then Jupiter and Saturn Sol1-d and -e, and maybe Mars Sol1-f? Who knows if they'll even discover Mercury, Uranus, or Neptune?

[@baladar1353]

If they label the planets by the distance from the Sun, it would be Sol (69???)-c. Mercure (a), Venus (b), Earth (c), Mars (d), Jupiter (e) and so on.

[@davidk1308]

That's if you use chemical propulsion, and that's not the only type of propulsion out there. There are multiple propulsion designs for fusion and laser sails that could reach 3-20% of the speed of light (or more if you're really ambitious), taking around a century to a couple decades to arrive. That's not outside the bounds of physics, just our current technical capability. We could have that kind of technology in the next couple centuries. And that's pretty tangible, from this moment in time, we could be closer to the era of interstellar travel than we are to the industrial revolution.

The animals there will be smaller than earth's because the planet has a radius of 1.6 times that of earth, and the higher the gravity the smaller the physically possible animals.

Favorite video on this channel so far

[@Storystein]

Thanks for this beautifully made and clear video! Up until recently I thought we lived around the 'most normal type of star' and OF COURSE every planet has a day and night cycle. Then I read a book that said that (at least in our Milky Way) red dwarves were by far the most common, and that all its nearby planets are tidally locked. It blew my mind! I still need to figure out how exactly this happens, but I find it fascinating!
