But, here's the interesting part:Astronomers have discovered a dwarf planet that's even farther away than Pluto -- so far, in fact, that its orbit reaches into a new edge of the solar system.
The dwarf planet's current name is 2012 VP113, and it is located in a "wasteland or badland of the solar system," said astronomer Chad Trujillo, head of adaptive optics at Gemini Observatory in Hawaii and co-discoverer of this object. His study was published Wednesday in the journal Nature.
You can read about this story at CNN.com and also at NPR.org.Trujillo's study also suggests that there could be a large planet that no one has seen, way out at 250 astronomical units, affecting the orbits of Sedna and the new dwarf planet. But this is only a theory; the planet has not been detected.
