Astronomers Discover Planet X (Kuiper Belt object bigger than Pluto)



See http://skyandtelescope.com/news/article_1560_1.asp

It's 97 AU out, it is a scattered-disk object, meaning that
at some point in its history Neptune likely flung it into
its highly inclined (44°) orbit. It's currently glowing at
around 18th magnitude in the constellation Cetus.
