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]Template:R/superscript 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
According to A.M. Garcia, NGC 19 is a member of the NGC 7831 group (also known as LGG 1), which contains at least 18 galaxies, including NGC 13, NGC 20, NGC 21, NGC 39 NGC 43, NGC 7805, NGC 7806, NGC 7819, and NGC 7836.[5]
