2017 FO161 is a large trans-Neptunian object from the scattered disc located in the outermost region of the Solar System. It is estimated to measure approximately 600 kilometers (370 mi) in diameter and currently orbits at a distance of about 78.5 AU from the Sun.[1][3][4] The object was first observed by American astronomers Chad Trujillo and Scott Sheppard using the 4-meter Víctor M. Blanco Telescope at the Cerro Tololo Inter-American Observatory in Chile on 23 March 2017.[2] Precovery observations were made by the Pan-STARRS-1 survey at Haleakalā Observatory and by the Dark Energy Survey with DECam, dating back as far as March 2012 and January 2016, respectively.[1]
