The Solar System has a new most-distant member, bringing its outer frontier into focus.
New work 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.
The work indicates the potential presence of an enormous planet, not yet seen, but possibly influencing the orbit of inner Oort cloud objects.
