NGC 1285 is a barred spiral galaxy in the constellation of Eridanus. Its velocity with respect to the cosmic microwave background is 5081 ± 12 km/s, which corresponds to a Hubble distance of 244.4 ± 17.1 Mly (74.94 ± 5.25 Mpc).[1] However, three non-redshift measurements give a much closer distance of 180.47 ± 3.24 Mly (55.333 ± 0.994 Mpc).[2] It was discovered by Heinrich Louis d'Arrest on 28 October 1865.[3]
