The icy Kuiper belt object 2002 LM60, was dubbed Quaoar (pronounced kwa-whar) by its discoverers. With the help of NASA's Hubble Space Telescope, astronomers have determined that it is the largest body found in the solar system since the discovery of Pluto 72 years ago. Quaoar is about 800 miles (1300 km) in diameter and is about half the size of Pluto.Illustration Credit: NASA and G. Bacon (STScI)Science Credit: NASA and M. Brown (Caltech)
