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). It was discovered by French astronomer Édouard Stephan on 22 November 1884.
According to the Simbad database, NGC 662 is a radio galaxy. It features a broad HI line and is classified a field galaxy, meaning it does not belong to the galaxy group nor a cluster and is therefore gravitationally isolated.
Three supernovae have been observed in NGC 662: SN 2001dn (type Ia, mag. 15.5), SN 2022ojo (type II-P, mag. 16.9), and SN 2024pcw (type II, mag. 18.7).
