166P/NEAT, also known as NEAT 8, is a periodic comet and centaur in the outer solar system. It was discovered by the Near Earth Asteroid Tracking (NEAT) project in 2001 and initially classified a comet with provisional designation P/2001 T4 (NEAT), as it was apparent from the discovery observations that the body exhibited a cometary coma. It is one of only three known bodies with centaur-like orbits that display a coma, along with 60558 Echeclus and 2060 Chiron. It is also one of the reddest centaurs.[1]

166P has a perihelion distance of 8.56 AU.[2]
