Astronomers discover new dwarf planet within our solar system

The object 2015 RR245 has joined the ranks of Pluto, Ceres, and other celestial bodies as a dwarf planet, The Guardian reports. In its tight elliptical orbit, 2015 RR245 would be twice as far from the sun as Neptune at the most distant point in its journey. A team of astronomers found the sphere of rock and ice while using the Canada-France-Hawaii Telescope on Mauna Kea in Hawaii, and have determined that it is 700 kilometers in diameter. The team is discussing possible names, though they will be under wraps for a few years while the dwarf planet is followed to better understand its orbit and trajectory.
