Yes, I am a geek.
I find this to be fantastically cool.
Named Sedna, after the Inuit goddess who created the sea creatures of the Arctic, the planetoid is 800 to 1,100 miles in diameter, or about three-quarters the size of Pluto, and probably half rock, half ice.
...Brown and his colleagues believe Sedna is the first known member of the long-hypothesized Oort Cloud, a sphere of material orbiting the sun that explains certain comets. If Sedna is part of the Oort Cloud, the cloud extends much closer inward toward the sun than previously believed.
I suppose I'm geek enough to think that's cool, but not so geek as to realize the Oort Cloud was just hypothesized. I kind of thought that was something they were sure about.
Anyway, it's still cool.
