Re: Definition of a Planet

<SNIP>

Some people want to have a requirement that the body does not produce
energy by any nuclear fusion mechanism. The problem with that is 2
billion years ago in Oklo, Gabon, Africa natural nuclear reactor was
formed when a uranium-rich mineral deposit became inundated with
groundwater that acted as a neutron moderator, and a strong chain
reaction took place.


That was nuclear fission, not fusion.

In any event, natural nuclear fission (not caused by a chain reaction) is
believed to be a major contributor to keeping the earth's core hot.
