NGC 1620
Galaxy in the constellation Eridanus
From Wikipedia, the free encyclopedia
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).[1] However, 20 non-redshift measurements give a closer distance of 130.02 ± 3.26 Mly (39.865 ± 1.001 Mpc).[2] It was discovered by German-British astronomer William Herschel on 1 January 1786.
