| Mar 31, 2021 at 22:04 | comment | added | EdvinW | Ah, I see. I interpreted it as the atmosphere having the same composition and pressure at the surface, but I suppose your interpretation makes sense as well. It's nice and a bit counter-intuitive how the atmosphere spread out on Earth would be less than 10 m deep :) (though it would be hard to take account for all terrain and the new elevation cause by the frozen oceans.) | |
| Mar 31, 2021 at 21:53 | comment | added | Starfish Prime | @EdvinW the OP states "same amount and percentages of gas and water vapor.". I'm assuming that Earth's atmosphere has literally been copypasted onto this other planet, which is a reasonable interpretation of the question. | |
| Mar 31, 2021 at 21:50 | comment | added | EdvinW | You seem to start off with the weight of Earth's atmosphere, correct? I'm trying to figure out if this is indeed the right way to go to produce a "comparable"(whatever that means) atmosphere on a smaller planet. If it is it might be worth a comment. | |
| Mar 31, 2021 at 21:46 | comment | added | Cygnus X-1 | Even better, I updated the other post to mention that it's basically a rounding error | |
| Mar 31, 2021 at 21:32 | comment | added | Starfish Prime | @CygnusX-1 right, the water vapour was missing (because everyone just talks about the dry mass of the atmosphere, and I didn't notice) and it is now in contributing a few extra centimetres. This will be dwarfed by the rest of the atmosphere, and the liquid and solid water already present on your world, but at least my list does now have all the major contributions to the frozen atmosphere thickness! | |

| Mar 31, 2021 at 20:53 | comment | added | Cygnus X-1 | Thanks! Does this account for the water vapor that would be present in the atmosphere? I'm told this would basically be a Snowball Earth scenario | |
