Is Naboo's core possible in real life? In Star Wars, the planet Naboo has a plasma core, instead of a molten one.

Can a planet really have a plasma core?
The mass will pull into the shape of the sphere if the body is massive enough. The body will then basically be in hydrostatic equilibrium. A planet like Naboo couldn't exist b/c the denser materials would move to the centre, and the lighter elements would then form an atmosphere around the solid core.

Plasmas require really high temps and a terestrial plantet couldn't compress gases to the temps required to completely ionize the gas. That and what I said about the way the planet would form. There's just no way that a shell of rocky material could be supported by gas pressure in that way. The whole thing would be really unstable.
