Encyclopedic overview
NGC 1620 is an intermediate spiral galaxy in the constellation of Eridanus. Its velocity with respect to the cosmic microwave background is 3,455 ± 4 km/s, which corresponds to a Hubble distance of 166.2 ± 11.6 Mly (50.97 ± 3.57 Mpc). However, 20 non-redshift measurements give a closer distance of 130.02 ± 3.26 Mly (39.865 ± 1.001 Mpc). It was discovered by German-British astronomer William Herschel on 1 January 1786.
