is a highly eccentric planet-crossing trans-Neptunian object, also classified as a centaur and damocloid, approximately in diameter. It is on a retrograde cometary orbit. It has a barycentric semi-major axis (average distance from the Sun) of approximately 286 AU.
History Discovery was discovered on 1 July 2010, by NASA's space-based Wide-field Infrared Survey Explorer (WISE). It was first observed by the Mount Lemmon Survey in 2009, extending the body's observation arc by 8 months prior to its official discovery observation by WISE.
Numbering and naming This minor planet was numbered by the Minor Planet Center on 31 August 2012 (). , it has not been named.

orbits the Sun at a distance of 9.4–547.2 AU once every 4643 years and 5 months (1,696,004 days; semi-major axis of 278.33 AU). Its orbit has an eccentricity of 0.97 and an inclination of 141° with respect to the ecliptic. It came to perihelion in December 2010 at a distance of 9.4 AU from the Sun. , it is 21.3 AU from the Sun. It will not be 50 AU from the Sun until late 2044. After leaving the planetary region of the Solar System, will have a barycentric aphelion of 563 AU with an orbital period of 4830 years. In a 10 million year integration of the orbit, the nominal (best-fit) orbit and both 3-sigma clones remain outside 7.7AU (qmin) from the Sun.
Physical characteristics
According to the surveys carried out by the NEOWISE mission, measures 44.2 kilometers in diameter and its surface has a low albedo of 0.057. More recent published data gives a diameter of kilometers with an albedo of .
