    How large a moon/planet need to be for the pressure caused by its own mass create heat in the centre?
    (after it is no longer a molten ball of magma like the center of the earth is now)

    If there is heat, and you could dig a tunnel deep enough (to the core if need be), could you generate power(for a space colony) from this type of geothermal heat?

    looks pretty warm. i would imagine that the core of Mars would be similar.


    Sometimes it is better not knowing than having an answer that may be wrong.

    No need to dig that deep to catch geothermal heat. And of course this heat could be used for power. Digging to the center of earth however seems borderline impossible. We ve barely scratched the surface right now. Much easier to catch the suns radiation, which is the source of most energies anyway.
    If you can't explain it simply, you don't understand it well enough.

    The answer. No. Just a note. There is no consensus among geologists as to what is the principal source of heat from within the Earth. There is initial heat when the Earth was formed, heat due to pressure, and heat generated via radioactive decay. The ratios of these 3 sources are open to educated speculation.
