Planet Nine? Not quite, but some astronomers think they've spotted a new dwarf planet
A possible new dwarf planet has been discovered at the edge of our solar system, so far-flung that it takes around 25,000 years to complete one orbit around the sun. The object, known as 2017 OF201, was found by researchers at the Institute for Advanced Study and Princeton University who were searching for “Planet Nine,” a hypothetical planet larger than Earth that is thought to orbit beyond Neptune.
