NGC 662 is a spiral galaxy in the constellation of Andromeda. Its velocity with respect to the cosmic microwave background is 5,397 ± 18 km/s, which corresponds to a Hubble distance of 79.6 ± 5.6 Mpc (~260 million light-years).[1] It was discovered by French astronomer Édouard Stephan on 22 November 1884.[2]
According to the Simbad database, NGC 662 is a radio galaxy.[3] It features a broad HI line[4] and is classified a field galaxy, meaning it does not belong to the galaxy group nor a cluster and is therefore gravitationally isolated.[5]
