2010 EL 139 is a trans-Neptunian object , one of the largest objects in the Kuiper belt . Opened in March 2010 by a group of astronomers from the University of Warsaw , led by Andrzej Udalsky ( Polish Andrzej Udalski ), under the OGLE-IV project, using a telescope at the Las Campanas Observatory ( Chile ) [2] . The 2010 EL139 orbits around the Sun in about 246 years, at an average distance of 39.29 a. e. The inclination of the orbit to the plane of the ecliptic is 23.02 degrees. The eccentricity of the orbit is 0.0677. Together with this object, Polish astronomers found four more large trans-Neptunian objects - 2010 EK139 , 2010 FX86 , 2010 KZ39 and (471165) 2010 HE79 [3] . Absolute magnitude 2010 EL139 - 5.1 m .
