Ok, since the game doesn't calculate things like chemical compositions, the answer "It depends!" isn't that valuable, but ...
Common, what substance is still gaseous at 287K and 1203atm???

Hydrogen, for one. I suspect there are several other common substances which are either gases or supercritical fluids at that temperature and pressure too.

Diatomic hydrogen, for one. At those conditions it is slightly below the gas/liquid phase boundary.

I'm not sure what the maximum possible atmosphere pressure is with SE's current atmosphere generation code, but as you said it is not yet a complete model.

edit: Ooops, Harb beat me to it. smile

The maximum pressure used to be 10000 atmosphere. It probably still is, unless something has been changed about it.

Can a planet keep an atmosphere that thick?




Love Space Engine!

In the OP's case, possibly. I mean, Venus can keep a 90 bar atmosphere though it's lighter and much hotter than the Earth. This world isn't much smaller than Venus and far colder, so I wouldn't be surprised if it could hold it.
