So if it is a geothermal processess then it cant be drive by sun, it is just to way far out. So what is driving this? Is it radioactive decay? If so then of what?
OR
Is it due pressure exerted by gravity? If yes then are these dwarf planets big enough to do so?
OR
Is it something else.

It is time that a few missions are planned for items beyond the orbit of Neptune.
