OK, that's a point. So, atmospheres that is not just temporarily - what moons do we have in the entire solar system of that kind?
Titan
Charon
Io???
I guess we have a small handful of moons around Jupiter, Uranus and Neptune, but i don't know much about them. I only know a couple of names, but not sure i can say anything about them, might even have great problems placing them by their rightful owner planet

The moons i like the most are those with a static atmosphere. I see the other moons as rocks more or less (sorry for my ignorance. I still want to explore them, but my priority has always been those with static atmospheres).
And i have anyother question i just thought of this morning:
All planets (with the exception of Pluto) beyond Jupiter are gasplanets. One thing i don't understand is why only the planets are made of gas while the moons are solid. Actually i would have considered it to be the total opporsite since i know a great pressure makes things more solid while low pressure makes it harder to keep the molecules static (more or less). I see the point of low pressure and high pressure, but i don't see why e.g. Titan is solid and Saturn is not.
