The object, designated 2003 UB313, is currently 97 Earth-Sun distances away - more than twice Pluto's average distance from the Sun.
It is in a peculiar orbit, unlike that of the other planets. Astronomers think that at some point in its history Neptune likely flung it into its highly inclined 44 degree orbit...."
