Could Planets Have Dual Cores Similar to Cell Structures?

[STC4476]

This i know sounds like a really odd question, but thinking along the Lines that i am.. i guess it has a sense of validity.

Could it be Possible, that Planets exist with Dual cores that internally orbit inside a Planet.. or partially joined. Thinking along the lines of Cell structure and how "Conjoined Twins" develop..

Probably not. When planets form or collide together to form a larger planet they are usually molten or become molten. This would probably preclude two cores forming. If one did exist, the planet would most likely be in a very unusual situation.
