2014 JM80 is a trans-Neptunian object from the scattered disc in the outermost Solar System, approximately 340 kilometers (210 miles) in diameter. It was first observed on 7 May 2014 by the Pan-STARRS-1 survey at the Haleakala Observatory, Hawaii, in the United States.[1] According to American astronomer Michael Brown, it is "possibly" a dwarf planet.[3][5]
