NGC 4632 is a spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background for is 2,061±24 km/s, which corresponds to a Hubble distance of 99.2 ± 7.0 Mly (30.40 ± 2.16 Mpc). However, 15 non-redshift measurements give a much closer distance of 54.12 ± 3.04 Mly (16.593 ± 0.931 Mpc). It was discovered by German-British astronomer William Herschel on 22 February 1784.
