How could the proposed theoretical temperature of the core of planet Earth (7,000 to 12,000 Fahrenheit) be hotter than the surface of the sun?
And what if smaller objects like asteroids and active asteroids (comets) are found to have surprising internal temperature?
The mystery of why planets are still hot
"One thing we can say with near certainty is that radioactive decay alone is not enough to account for Earth's heat energy," Stuart Freedman of the U.S. Department of Energy's Berkeley Lab said in a statement. "Whether the rest is primordial heat or comes from some other source is an unanswered question. This is what's called an inverse problem, where you have a lot of information but also a lot of complicated inputs and variables."
The earth continuously generates about 44 terawatts of heat, according to measurements from approximately 20,000 boreholes all over the world. It's this heat, and how it affects substances in the core and mantle, that leads to the gradual motion of continents and the creation of the earth's magnetic field. Exactly how this heat is generated has been difficult to measure, since the inner layers of the planet can't be probed directly.

Electrical heating of planets?
Using observed data from the physical experiments conducted using SAFIRE, Montgomery mentioned an electromagnetic mechanic might explain why planets cores and surfaces are still hot. The video below starts at the point where he reviews the temperatures of the SAFIRE chamber and the anode etc.
For example the centre of the anode may be 2500C but the surface of the anode was of the order of 1 magnitude cooler.
The radiation leaving the surface of the anode does so at the speed of light. The temperature takes a lot longer to migrate/conduct through the dense core material.
Could this be a heating mechanism for planets that should be frozen cold by now if they are as old as they say they are?
Geomorphology suggests that geological features found on asteroid Vesta (rocky material created from and at the beginning of our solar system and perhaps the universe) have to be formed by flowing water.
Could an electrical discharge/plasma process on asteroids or especially an active asteroids (comets) possibly explain how you could get water erosion features on them if it melts any ice supposedly found on or in them?
