Newly discovered dwarf planet could challenge what we know about our solar system
While Pluto might have been stripped of its full planetary status, thanks to a shift in official definitions, a newly discovered planetoid could actually hint at the existence of a "super-Earth" in the far reaches of our solar system. The ball of rock and ice, known as 2012 VP113, is estimated to be 250 miles wide, and has the most distant known orbit of our sun -- currently around 7.7 billion miles, extending to around 42 billion at its farthest. 2012 VP113 was spotted using the Dark Energy Camera in Chile, after a series of time-lapse photos captured it moving across the night sky.
