Is it possible that a planet could support life using its own heat and elements?

Question

For example; lets say a planet at the same distance from the sun as Neptune could have enough geothermal heat to make the air temperature warm in spite of how far it is from the sun. Could this be possible somewhere in the universe? Or could there be another scenario in which a planet is able to keep warm and harbor life in spite of being so far away from the sun.

Answer 1

Of course anything is possible in the universe. The earth and sun system of life is a fluke so there is lots of room for other accidents in the universe.

Answer 2

Maybe short term, but to generate enough heat to support the planet would use up the planet's heat very quickly.

Answer 3

I don't see why not. Or, for that matter, why there couldn't be another planet at about the same distance from its Sun as we are from ours.

Answer 4

well maybe it would need alot but most likely not, lets just say for a minute that there were time to build hughe ware houses that had lights to grow plants properly. Then maybe in minute land you might have a chance, the sunlight does alot of basic necessity's for the growth of life, you need to go more in to depth how would river's and oceans not be frozen or algae grow in them providing the beginning of the food chain for marine life.life is very delicate, its like human emotion one wrong move and everything may go good or bad or something in between, maybe never thought of.
