hi i just found a selena with an atmphosphere its the moon of a gas giant a really nice moon system with lots of desert one of the moon is really close to the gas gian and got alot of moutains. but ok the question is i though selenas was planets without atmphosphere. The atmphosphere is almost nonexistent but you can see the atmphoshere in orbit so its a strong atmphosphere with color. Name. RS 8403-228-9-68740939-128 6.3
They can get far thinner and tenous than that, in fact, check out 11.2 of the same system. Granted, that ones atmosphere is probably frozen out, but I've seen tenous atmospheres like that in moons further in.
