labellementeuseOH OH ITEM OF COOLNESS:
Tenth Planet Discovered!
That is kind of cool. Although, you know, if Pluto is 40AU out and Planet X is 97 AU* out, is that a planet or just a supah-large Oort Cloud object? How far out is the Oort Cloud anyway?
Okay, Wikipedia Says 50,000-100,000 AU out. Which, dude, is a long way to travel for long-period comets, I never really thought about that before. Anyway. So I guess not a supermassive Oort cloud object. And it's bigger than Kuiper belt objects because they think it's bigger than Pluto which kind of sits on the fine line- some people think it's a planet, some people think it's a big Kuiper belt object.
Um, anyway. Yay, new planet? I don't really have an appropriate icon for this...
*1 AU=Astronomical Unit= distance from Earth to Sun
