Just beyond Neptune lies a ring of small, icy worlds that offer insight into the formation of our Solar System, and scientists using the Canada-France-Hawaii Telescope on Maunakea, Hawaii, just discovered a new dwarf planet in this region that rivals Pluto and Eris in visibility. It’s called RR245 and in this case, size matters — many of the worlds in the farthest reaches of the Solar System are too small and dull for Earthbound scientists to study. Basically, when it comes to post-Neptune dwarf planets, the bigger and brighter, the better.
