NGC 19 is a spiral galaxy in the Andromeda constellation. Its velocity with respect to the cosmic microwave background is 4,465±23 km/s, which corresponds to a Hubble distance of 214.8 ± 15.1 Mly (65.85 ± 4.62 Mpc).[1] However, 12 non-redshift measurements give a closer distance of 202.16 ± 9.32 Mly (61.983 ± 2.857 Mpc).[2] It was discovered by American astronomer Lewis Swift on 20 September 1885.[3][4] It is often incorrectly listed as a duplicate of NGC 21.[1]

NGC 7831 Group
