It was discovered on 16 November 2011, by astronomers with the LINEAR at the Lincoln Laboratory ETS near Socorro, New Mexico, in the United States. Orbit 2011 WL 2 is a potentially hazardous asteroid (PHA), but has a well determined orbit with a 10 year observation arc. 2011 WL 2 will pass at a distance of 0.0056 AU km mi on from Earth on 25 October 2077. For comparison, the distance to the Moon is about 0.0026 AU (384,400 km). 2011 WL 2 appears on the list of PHA close approaches issued by the Minor Planet Center (MPC), with the next close approach in the year 2038.PHA Close Approaches To The Earth http://www.minorplanetcenter.net/iau/lists/PHACloseApp.html Minor Planet Center 2015-05-29 The Jupiter Tisserand invariant, used to distinguish different kinds of orbits, is 5.7.
