(532037) 2013 FY27 (provisional designation 2013 FY27) is a trans-Neptunian object and binary system that belongs to the scattered disc (like Eris).[8] Its discovery was announced on 31 March 2014.[1] It has an absolute magnitude (H) of 3.2.[3] 2013 FY27 is a binary object, with two components approximately 740 kilometres (460 mi) and 190 kilometres (120 mi) in diameter. It is the ninth-intrinsically-brightest known trans-Neptunian object,[9][failed verification] and is approximately tied with 2002 AW197 and 2002 MS4 (to within measurement uncertainties) as the largest unnamed object in the Solar System.
