    2014 NW65 is a centaur (a minor planet in the outer solar system), approximately 220 kilometers (140 miles) in diameter, about the same size as 10199 Chariklo. It was first observed on 14 July 2010 by the Pan-STARRS-1 survey at the Haleakala Observatory, Hawaii, in the United States.[4] According to American astronomer Michael Brown, it is "possibly" a dwarf planet.[2][5]
