Large 'Planet X' may lurk beyond Pluto - USATODAY.com


Large 'Planet X' may lurk beyond Pluto - USATODAY.com: "An icy, unknown world might lurk in the distant reaches of our solar system beyond the orbit of Pluto, according to a new computer model.

The hidden world — thought to be much bigger than Pluto based on the model — could explain unusual features of the Kuiper Belt, a region of space beyond Neptune littered with icy and rocky bodies."
