    1. So is Titan, I find this cool, like our solar system would have more planets if they didn’t orbit another planet. One may argue that they are less massive / dense, but I wouldn’t blame them for it, developing beyond frost line comes with different development and composition, one that favors ice and volatiles.

    2. If Ganymede wants to be called a planet, it ought to break orbit and go independent like Mercury. It’s not easy going solo.

      Always feel bad for Mercury. Standing on the frontine for 4 billion years and doesn’t get anywhere near the love of the other ones behind it. 

    4. Mercury could be the core of a larger planet and the outer layers got blasted off by collisions.
