2000 DG8 is a damocloid centaur[2] discovered by the MIT Lincoln Laboratory on 25 February 2000.[1] It is one of about 60 known minor planets with a retrograde orbit around the Sun.[3][4] It was last observed in 2001 when it came to perihelion (closest approach to the Sun),[2] and will next come to perihelion in April 2036. Given the comet-like orbit and low albedo it may be a dormant comet.
