Chemical composition of atmosphere
Update that everyone wanted for a very long time: chemical composition of atmospheres. Current implementation is far from complete and may give unrealistic results.
Good old CO2 atmosphere:
This is a sauna planet - looks like a terra with boiled out oceans. Not a far future of Earth:
Terra with life - atmosphere seems suitable for humans... Well, no, partial pressure of O2 is just 0.089 atm (humans needs at least 0.16 atm):
This moon could be a titan if it were a bit colder:
This ice giant seems lost all of its H2 and He... This is a "chtonian" planet. Its radius must be a few times smaller than showed here, but this is not implemented yet.
