A new dwarf planet has been found in our solar system, its name: 2012 VP113. The new dwarf planet is a long ways out, coming no closer to the sun than 80 AU.
Not just that, but it sounds like there is a potential of a new planet out there, possibly up to 10 times the size of the Earth! This remains to be seen though.
This from the Carnegie Institute:
New work from Carnegie’s Scott Sheppard and Chadwick Trujillo of the Gemini Observatory reports the discovery of a distant dwarf planet, called 2012 VP113, which was found beyond the known edge of the Solar System. This is likely one of thousands of distant objects that are thought to form the so-called inner Oort cloud. What’s more, their work indicates the potential presence of an enormous planet, perhaps up to 10 times the size of Earth, not yet seen, but possibly influencing the orbit of 2012 VP113, as well as other inner Oort cloud objects.
