(468861) 2013 LU 28 is a planetoid that was discovered on June 8, 2013 as part of the Mount Lemmon Survey and belongs to the group of Trans-Neptunian objects . The asteroid has been in a highly eccentric orbit around the sun for over 2200 years . The eccentricity of its orbit is 0.95, whereby this is inclined 125.36 ° to the ecliptic , so that it runs retrograde around the sun.
It is assumed that the large retrograde planetoid (468861) 2013 LU 28 as well as the two centaurs (342842) 2008 YB 3 and 2011 MM 4 are visitors from the Oort cloud .
