Cobalt Planetary Core?

[Hypok]

Hello, would it be possible/reasonable for a planet to have a core made of Cobalt? Sorry if this is in the wrong area, I'm new here.

highly unlikely. Iron is about 1000 times as abundant as Cobalt in the universe.

But still theoretically and physically possible despite unlikelihood?

The physics is possible, but if you found one...
