Encyclopedic overview
NGC 1642 is a spiral galaxy in the constellation of Taurus. Its velocity with respect to the cosmic microwave background is 4575 ± 3 km/s, which corresponds to a Hubble distance of 220.1 ± 15.4 Mly (67.48 ± 4.72 Mpc). However, one non-redshift measurement gives a much closer distance of 69 Mly (21.3 Mpc). It was discovered by German astronomer Heinrich d'Arrest on 29 December 1861.
