A scrawny dwarf planet nicknamed the Goblin has been discovered well beyond Pluto.
A round, frozen world just 186 miles (300 kilometres) across, the Goblin was spotted by astronomers in 2015 around Halloween, thus its spooky name. But it wasn’t publicly unveiled until 2 October following further observations with ground telescopes.
Scott Sheppard of the Carnegie Institution for Science, one of the astronomers who made the discovery, said the Goblin is on the small end for a dwarf planet. It is officially known as 2015 TG387 by the International Astronomical Union’s Minor Planet Centre
