Is Triton Neptune's moon's core cold or hot?

Question

Well, Triton might have a liquid ocean benath the icy surface, but I know learning Triton have a active volcano activity. If it have volcano activity then it is probably hot. Is probably the books I have said that.

Answer 1

Cryovolcanoes on Triton shoot out dirt water, not magma.

Answer 2

I don't know.



It's surface is -235 C, so 42 K, very cold indeed.



The volcanic activity is eruption of liquid nitrogen, or a mixture perhaps of liquid nitrogen and methane so still very cold, just warmer than the surface.

So you don't need much heat to get volcanism. It's not even eruption of water, so the volcanoes are at temperatures well below 0C.



That doesn't mean that the core has to be cold as well, I suppose it could be warmer than the surface just as our Earth's core is much hotter than the lava that you get from volcanoes.



So I don't know for sure maybe someone else who answers this question will know but perhaps this will help.

Answer 3

Due to certain charcteristics about Triton, it is safe to assume, but not define, that Triton may have a heated core at its center.
