An international team of astronomers discovered the dwarf planet identified for now only as 2015 RR245. Using the telescope on Mount Maunakea, Hawaii, as part of the OSSOS survey, they found 2015 RR245, whose orbit is in the Kuiper belt, the area of ​​the solar system beyond Neptune where there are many icy celestial bodies.

The diameter of the dwarf planet 2015 RR245 has been estimated at around 700 kilometers (about 435 miles), which means it’s a bit smaller than Ceres. In the Kuiper belt there are 17 objects larger that that so this discovery is not at the level of that of a planet or at least of a dwarf planet the size of Pluto or Eris. However, each object discovered out there can tell us something more about the history of the solar system.
