I dont think we are 100% certain what is happening inside the core on our own planet yet.

But it is a lot more complicated than the moon.

TL;DR "The Moon is not made of green cheese after all"

Do we know that cheese cannot be compressed to the density of iron?

The moon being hot enough for a liquid outer core is insane to me. I wasn't aware that tidal heating was so powerful.
