A planet past Pluto? Astronomers redefine the solar system's edge
« on: March 30, 2014, 08:52:06 AM »
Our little corner of the universe just got a little more crowded.

Scientists at the Carnegie Carnegie Institution for Science announced Wednesday the discovery of a new cosmic neighbor -- a distant dwarf planet named 2012 VP113 that was found spinning in the depths of space well past Pluto. Its existence suggests there may be another actual planet out there, they said, a rogue giant ten times bigger than Earth orbiting in the distant blackness.

Newly found VP 2113’s closest approach to the sun is about 80 astronomical units and its greatest distance is 452 astronomical units. The small world is roughly 280 miles (450 kilometers) wide, less than half the estimated diameter of Sedna.
