I would think being so close to the sun would have to do with it, and maybe being small, so that energy can actually get through to the core. That or the Vex did it.

If it's due to the energy from the sun radiating inward then the outside should be molten too, yeah?

Not everything melts in the same temperature range.

Maybe it's due to tidal forces from the sun?

Now I feel like an idiot, that's the obvious(ish) explanation.
