NGC 4632
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.
It was discovered in 2023 that the galaxies NGC 4632 and NGC 6156 are surrounded by a disk of cold hydrogen orbiting 90 degrees around their disks. These are the very first polar-ringed galaxies discovered through radio wave observations. These observations were made as part of the WALLABY astronomical survey.
According to A. M. Garcia, NGC 4632 is a member of the NGC 4666 Group (also known as LGG 299). This group has 3 members, including NGC 4666 and NGC 4668.
