(471165) 2010 HE 79 is a large trans-Neptunian object in the Kuiper belt . It was discovered in May 2010 by a group of astronomers from Warsaw University , led by Andrzej Udalski ( Polish: Andrzej Udalski ), as part of the OGLE-IV project, using a telescope at the Las Campanas Observatory ( Chile ). [2] The 2010 HE79 revolves around the Sun in about 237 years, at an average distance of 38.28 a. e. The inclination of the orbit to the ecliptic plane is 16.07 degrees. The eccentricity of the orbit is 0.1903. Together with this object, Polish astronomers found four more large trans-Neptune objects - 2010 EK139 , 2010 FX86 , 2010 KZ39 and 2010 EL139 [3] . The absolute magnitude of 2010 HE79 is 5.3.
