Hubble Space TelescopeNASA’s Hubble Space Telescope spots an object beyond the orbit of Pluto, and approximately half the size of Pluto – the largest object discovered in the solar system in over 70 years. With a circular orbit that’s a billion miles further from the sun than Pluto, the body is determined to be approximately 800 miles in diameter. Quaoar is believed to be the largest Kuiper Belt object discovered to date, though its thunder will be stolen a few years later with the discovery of Eris and the demotion of Pluto to a dwarf planet.
