Retained Molecular Weights of Bodies of the Solar System

[Holo]

That other thread about Eve and Duna got me thinking about what gases would actually be found in those atmospheres. Coincidentally, at the same time, I read that atmospheric composition can be found out by looking at which gases can escape. I happen to have the equations for this bookmarked, so without further ado, here is some table of molecular weights and stuff! I scaled the distance from the sun up by 10 and the escape velocity up by √10 when I entered them into the equations, because otherwise pretty much nothing can have an atmosphere.

In conclusion, give Tylo an atmosphere plz.

I think one of Jools barren moons needs an atmosphere, id love to see a Titan (isn't that the name of it?) type of atmosphere on a moon

Tylo is the barren one that's capable of supporting the most atmosphere, so it's the logical place to put it.

I think I kinda understand it, but whats CH4?

...Methane. Seriously just google stuff like this.

Good job on making a document on this. Is there a google doc I could have a look see on?

Also, is the retained gasses mean that it can hold that gas and any lighter? Or is it that gas and any heavier?

Google is almighty

But that would ruin the whole challenge of landing on Tylo! You shouldn't be able to use the atmosphere to your advantage for landing, so maybe just a very small, thin atmosphere that does not allow any parachutes to deploy or cause too much drag.

Any gas and heavier. Heavy gases need more energy to reach escape velocity, so they are easier to retain.
