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).[1] Additionally, 12 non-redshift measurements give a distance of 67.21 ± 2.35 Mly (20.608 ± 0.721 Mpc).[2] It was discovered by German-British astronomer William Herschel on 3 March 1786.[3] 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.[3]
