[QUOTE="painandgreed, post: 2483795, member: 24969"] Something like an earthlike planet around a larger than jupiter planet should be fine. It would be more of a duel planet system than a moon/planet system. The distance that the earthlike planet would have to orbit the gas giant would more than likely put it outside most of the harmfull radiation from the gas giant. The Em radiation could warm the earth-like planet however, it's been shown that even a planet that is tidally locked with one face always facing towards the sun can still maintain a liveable temperature on the darkside due to a greenhouse atmostphere. Make it a mostly water world like ours and you're going to get a side of clouds that will come to the darkside and condence and give you your rainforest. Having one side always facing the sun is the werid problem. One side facign the sun and one side always facing the gas giant would be the easiest configuration but then you'd have this constant huge full moon in the world. Perhaps mostly obscured by clouds but if the planet is close enough to make the earth-like planet habitable, it's still going to be pretty bright. You could have the earth-like planet rolling over and under the gas giant so that the gas giant moon is always at the horizon. Tilt it a little and adjust the rotation and you could have seasons. I don't see any long term problem with habitablity of the planet unless you make it small and it would otherwise lose atmosphere to space (like Mars). [/QUOTE]
