NGC 4129
NGC 4129 is a barred spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background for is 1,534±25 km/s, which corresponds to a Hubble distance of 73.8 ± 5.3 Mly (22.62 ± 1.63 Mpc). Additionally, 12 non-redshift measurements give a distance of 67.21 ± 2.35 Mly (20.608 ± 0.721 Mpc). It was discovered by German-British astronomer William Herschel on 3 March 1786. It was also observed by Heinrich d'Arrest on 15 March 1866, causing it to be listed twice in the New General Catalogue, as NGC 4129 and as NGC 4130.
