7066 Nessus /ˈnɛsəs/ is a very red centaur on an eccentric orbit, located beyond Saturn in the outer Solar System. It was discovered on 26 April 1993, by astronomers of the Spacewatch program at the Kitt Peak National Observatory in Tucson, Arizona.[1] The dark and reddish minor planet is likely elongated and measures approximately 60 kilometers (37 miles) in diameter.[5][13] It was named after Nessus from Greek mythology.[1]
