Well, Venus would look like this!
And then my favorite, most spectacular, Saturn!!!
I used to wonder Surely there are lightning strikes even in that kind of atmosphere so why hasnt it gone the way of the deathstar… You still need oxygen to combust i guess. And a fair amout for a moon that size
If any planet of jupiter or Saturn stature came near us, we would either be sucked to death like a meteorite by its Gforce, or we would start orbiting around it like a moth. Either way, our atmosphere would go like a fart. Dead, no life on earth
