The Solar System has a new most-distant member, bringing its outer frontier into better focus. Astronomers reported today the discovery of a distant dwarf planet called 2012 VP113. 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, that is possibly influencing the orbit of 2012 VP113 as well as other inner Oort cloud objects. Up to now, only one dwarf planet, Sedna, was known to exist in the Oort cloud. But the newly found 2012 VP113 has an orbit that stays even beyond Sedna, making it the furthest known in the Solar System.
