The 10th planet is tentatively named Xena.

BBC News: 10th Planet has moon companion

I think they should keep it that way. Sure, it was just a joke, but what a joke! This is tremendous.

It's like a bit I would do (okay, have done in various forms). When family or friends are pregnant with a girl I suggest "Xena: Warrior Princess" would make an excellent name. My god-parent's daughter named her daughter "Gabrielle" after I made such a suggestion, but I'm entirely certain that it was coincidence and not causation.... or was it?

I love doing the oblivious-guy-bit where I pretend to think Xena is actually in Greek mythology.

I loved the show. I love most shows where hot girls kick ass. I didn't care for it when they tried to be too campy, but most shows are a mixed bag, and you take the good with the bad.

Still, they named a planet (for now) Xena. How great is that?!
