[@Axiomatic75]

Yeah, it does sound close until you remember just how fast light travels. I doubt humans will ever make it that far away from earth. The best we can probably do is send robots/ai once we can accelerate a ship to a meaningful fraction of the speed of light.

no panic, surface gravity is 31,8 m/s² on LHS 1140b. It's really hard to get off Earth with s.g. of 9,8 m/s². So probably they can't leave their planet. The escape velocity must be huge. For those who want to go there: you can check in every time you like but you can never leave lol

[@hdbrot]

The formula for the escape velocity is v = sqrt(2gr), where g is the gravitational acceleration on the surface and r is the radius. So LHS 1140b has around sqrt(6) times the escape velocity on earth. And it also gets easier with more height. So I think that‘s not too high but of course also not that easy.

The surface gravity actually is a lot less (about 18.3 m/s²), the number 31.8 is outdated.

[@Evan.13239]

I've always been interested in the idea of a science fiction story set on an eyeball planet that uses the shadow of a moon to run caravans across the scorched side of the planet.

[@zephyramethyst9455]

that idea is cool & creative asf

[@gkw9882]

The eyeball is on the sunny side, it's liquid because if always faces the sun. The other side is frozen, how about a giant flying mirror to reflect sunlight, so they could explore the ice.

[@marcozelioli]

That sounds like a fire concept! Just imagine how life could adapt to such conditions! There could be some creatures that go into hybernation until the moon blocks out the scorching sun again. There could be swarms of flying/ jumping, migrating insectoids following the shadow of the moon. Fish that come to the surface when the moon covers the sun and dive back into the depths when it moves on. There could be swarms of flying tartigrade/ plancton-like creatures escaping the heat by flying high above the surface when the sun shines and only coming back down to mate when the moon blocks out the light. And let's not even get started on the plants! They would probably be much lighter colors like white/ silver (similar to the desert ant) to reflect most of the light. These flowers would bloom during the eclipse when the moon blocks out the sun. There could be entire ecosystems of floating reflective algea/ plants where underneath fish live in the root system and provide important nutrients. Obviously, your idea needs some more polishing, I think in order to make it work, you would need at least 2 stars to illuminate both sides of the planet constantly. The ideas here are endless. You could call the book something like "scorching" or "eclipse". Get to writing already!

[@marcozelioli]

@gkw9882 I think he knows that. He was just toying around with the opposite idea.

[@abaddon1371]

Scorched? Wasn't the "eyeball" thought to be formed by water on the side facing the red dwarf and the rest frozen over? Anyways, made me think of the prison planet Crematoria in the movie "The Chronicles Of Riddick" Where it is either scolding hot or freezing, with only a small window one is able to move on the surface of the planet.

[@mikal5576]

TWO QUESTIONS 1- would the planet have a huge ice wall? 2- would there be huge sweeping winds across the one patch not ice? Which I would then think would make the surface unbearable.

[@Johnny_Appleweed]

Answer We have no further information from which to draw conclusions either way.

[@JamesDavy2009]

If the planet was an ocean world, the night side would be more impassable than the Arctic Ocean. Add an Earth-like atmosphere and there would be a massive thermal where its sun would be at the zenith, driving convective wind currents and making the temperature difference less extreme. There could even exist a perpetual storm at that point.

[@pauloakes6952]

Or they’d send probes or satellites around the planet to figure it out. That requires intelligence though.

[@skippi99r32]

Assuming there were intelligent beings on one of those planets similar to human beings, they would probably come to the same conclusion that their planet is a sphere just using ground tests

[@rayfighter]

​@@pauloakes6952he said civilization, so I think that the intelligence is kind of a part of the package. Although I would be still curious if they could develop a cosmic program on an ocean world. Or want to.

[@bbartky]

😂I hadn’t thought about that. I think their religion and culture would be wild too since their world beyond their “eye” would be uninhabitable and probably unreachable. However, as the other commenters pointed out I think as long as they could develop scientific methodology they would be able to determine that their world was round. For example, they could look at the angle their sun makes at the same “day” and time in different parts of their “eye”.

Life, as we know it on Earth, relies on daily change in temperature and the non-equilibria associated with it. It is hard to imagine that life could be created and maintained in a world that is perpetually locked with its hosting star. The chance for it to have a magnetic field and a magnetosphere is slim.

[@MarcVL1234]

Frozen on the dark side, but not necessarily frozen all the way down. Water ice is a good insulator, & esp if there is internal geological activity or strong tidal forces, there could easily be liquid oceans under the ice on the dark side. It would be a very interesting biosphere if there was one.

[@franciscooyarzun2637]

Correction: If a tidally locked planet is mostly rock, but has enough water to cover it completely, and is cold enough that said water is frozen, except in the substellar region, then, in the long run, the result would have to be that: • The substellar region becomes a desert, surrounded by a massive wall of ice,  ice that is continually melting; thus there should exist permanent rivers and lakes. • The wall of ice is constantly creeping inward (toward the substellar point),  pushing rock along, like a bulldozer, and this would pile up into mountains,  but running water and creeping ice would carve deep canyons. • All the evaporating water forms a perennial ring of snowing clouds. • Around the substellar point, there should be a landscape gradient suitable  for savannah, “lake region,” forest, montane ecosystems, and tundra.

[@ETLee-db6cn]

Much depends on the temperature of the dark side of the planet. If it's cold enough to freeze the inert gas in the atmosphere (nitrogen) then there might be little atmosphere at all.

It’s about how life evolves in warm water, and where there is movement to coax the primordial oozes. Yes, when we get to our level, we couldn’t live there. But that’s where we started

[@sigisoltau6073]

​@@AnthOny-gl7ljWell, yeah, but that's here on earth. On an ocean world like this the oceans would be tens of miles deep in the shallow areas. There'd be no continents like here, hence the name ocean world. Water makes up roughly 0.023% of earth's mass. With an ocean world that's roughly 20 to 50% of the mass.

[@j.f.fisher5318]

So an eyeball frozen water world, that's interesting. I'm imagining a world that's probably not this one but just a bit hotter where the water on the closest part where the melted patch is evaporates away. Then the water vapor is caried to the far side and falls as snow that builds massive ice sheets until nearly all the water is ice on the far side and the near side is a desert. But the mass of the ice on the far side pushes glaciers toward the hot side all around the planet. And the glaciers melt into rivers that flow into the desert and dissappear into the sand but with greenery on their banks.

It would certainly be an interesting world to study up close. Being that large it's more likely to have held onto some atmosphere, and a magnetic core could be possible. It also may not have had active plate tectonics like our planet if it ever did, since a similar moon to ours is highly unlikely to stick around if it even forms. Any water would mean it has some interesting chemistry on the surface, especially if it isn't alive and the planet is as earthlike as it currently seems. It kind of sounds like darwin IV being so close, and considering everything else.

Very interesting, thank you again. Ordinarily when I hear of planets around red dwarfs that 'may be suitable for life' I automatically think "ah, no." Tidally locked planets close-in to such 'flare stars' will be at very best barren rocks... ...but an 'ice-shell world' with or without an 'eye' with an abundance of water may be in a better position than most to be technically habitable. I hope now or in the near future we will have the ability to check such bodies in greater detail.* *My gut tells me the solar system is an island with life in a very large and barren universe. Indeed, it's very likely that even here only Earth has life. But that's no reason not to look, and I'd be happy to be proven wrong.

[@jgkitarel]

If there is any life on that world, it will likely be fairly deep in the ocean due to the fact that it orbits a red dwarf. Red dwarfs tend to be very variable stars despite how relatively cool they are and can pump out a lot of radiation and flares with no warning and quite often. Any life on that world would have to adapt to that if it wants to survive and thrive. And even if life does or can exist on that world, that doesn't mean that it is habitable for us.

[@DafSpi]

Since this planet is likely tidally locked and likely has a warm and cold side, I wonder if there is some kind of air circulation and ocean current which moves the warm air and water around the planet, which could make certain regions of the planet even more temperate.

If we can get Breakthrough Starshot tech to be common place, perhaps launched from the moon, we would learn so much more about the cosmos. It would be great if LHS 1140b had rotation, and land.

[@ericjohnson6675]

Wonder if there could be some form of surface dwelling lie on the ice fringes next to the oceans. If there is aquating life, then a jump onto the ice around it would give an evolutionary advantage similar to how life, plant and animal, took advantage of a barren terrestrial surface on Earth long ago. No predators or competition so a great refuge. A lot of assumptions but an interesting speculation.

I always try to leave a little room for some of the estimated mass of any exoplanet actually being a sizable moon, possibly even a double planet setup, given the measurement sensitivity of the currently existing instruments probably isn't high enough precision to tease that detail out of the data.

Apparently, planets with a massive partner like ours are relatively rare.

Have you considered the effect of tidal locking on the planets ability to maintain a magnetosphere of any consequence for long enough for even basic biology to take hold if the planets angular momentum has changed from rotation to orbital velocity then surely the core's rotation is also going to be restricted and eventually held by the stars gravity

[@thomasgeorgecastleberry6918]

Yeah;- Flash Gordon told me about that planet, years ago!

[@AwesomePossum1987]

and this is in our galactic neighborhood. amazing, maybe life isn't as uniq as we think, but intelligent lifeforms like us are very uniq.

Would the water provide enough protection from the large solar flares that red dwarfs throw?

[@paulanizan6159]

I have problems with locked in planets circling red dwarfs which are much more active than our sun. I would prefer to look for stars much more similar to oursun.

Sounds like a DnD setting for me to map out.

I wonder what the average g force of all the terrestrial (and mostly terrestrial) planets is. Like, is it more likely for us to find lower than one g, or higher than one g? Because that impacts future plans. Long, long time future plans.

With a warm side, liquid, and atmosphere. There should be a wind on the planet. The wind direction might be able to be roughed out if it's known it's orbit and if it has a slight different season because. Then at that, it might not look an eyeball. It might look more a sideways heart shape area on it. If the wind due to the forces that be still make the wind decide to travel around the planet in one direction. Icebergs on one side might then break off do to the circulation of the warm air. Then melt away and the warm air current then might create an inlet opposite to.

To a civilization on an eyeball planet, there would essentially be a scientifically verifiable center of the world. At the very least, a center of the habitable world
