Astronomers discover ‘eccentric’ dwarf planet

1. Bad subheading they wrote - it's not 'orbiting Neptune', or 'the space beyond Neptune', at all

It orbits the Sun, beyond Neptune. And "heading out twice as far as Neptune" is selling it short - it's already twice as far away as Neptune - over 63 AU. It will end up, eventually, about 120 AU away, which is roughyl 4 times as far as Neptune. Here's a better write-up: http://www.space.com/33387-dwarf-planet-discovery-2015-rr245.html

It's not the largest object in orbit that has yet to be named. 2007 OR10 is about 1300km across, compared to the 700km of 2015 RR245. And that hasn't yet been officially declared a dwarf planet, though it's been known about for 8 more years.
