[<1/1,000,000th%]

The 10th planet is nicknamed Xena until it is officially named.

Unfortunately, 2003 EL61 doesn't have a name yet.

Isn't that where the Cyber-Men come from?

I always thought that "Planet X" was a cool name, particularly before they found the thing. They knew it had to be there from the gravitational effects, which is also why they used to think that Pluto was much bigger than it really is.

"Planet X" has it all: mystery, science and it's the Roman numeral for 10, and planets all have Roman names anyway.

Of course, according to ALF, the universe already named it Dave. Or it might've been Alvin.
