Omg alliballi, those are definitively my favorite too! besides pluto of course :).
Jupiter. How could you not love a giant gas planet with a big red spot? Also, it is the only reason I became friends with one of my best friends, a fellow nerdfighter.
I don't really know but whenever I think of a specific planet it reminds me of Sailor Moon and then that is how I choose the planet heh heh
I rather enjoy Earth.
