is a large trans-Neptunian object orbiting in the scattered disc of the outermost regions of the Solar System, estimated to be around in diameter., it is approximately from the Sun, and will slowly decrease in distance until it reaches its perihelion of 38 AU in 2142. The discoverers have nicknamed it "DeeDee" for "Distant Dwarf".
was discovered by a team led by David Gerdes using data collected by the large camera The [Dark Energy Survey|Dark Energy Camera]. The discovery was announced by the Minor [Planet Center] on 11 October 2016. Assuming its nominal diameter of, it reflects just 13 percent of the sunlight that hits it. The earliest known precovery observations of were taken at the Mauna Kea Observatory on 15 October 2006.
has not yet been imaged by high-resolution telescopes, so it has no known moons. The Hubble Space Telescope is planned to image in 2026, which should determine if it has any significantly sized moons.
