Eureka!

Possible 10th planet discovered

They've named it Sedna, after the Inuit Goddess of the Ocean. It's 3 billion km past Pluto. The debate is whether it qualifies as a planet (some people have tried to yank Pluto's status, due to it's size, or lack thereof).

I've always thought there were 10 planets in the system, and that someday we'd have the technology to see it. Hope Sedna gets to keep the distinction.
