The object, , is currently in the shape of a potato, is roughly the size of Pluto , and rotates on its axis every 4 hours. The top layer of the object is covered in a thin layer of an ice like substance and has a rocky center. Simulations show that the object is in an unstable orbit. "It's a bit like the story of Mercury . Mercury got hit by a large object early in the Solar System. It left mostly a big iron core, with a little bit of rock on the outside. This is mostly a rock core with a little bit of ice on the outside," added Brown.
