NGC 4129 is abarred spiral galaxy in theconstellation ofVirgo. Its velocity with respect to thecosmic microwave background for is1,534±25 km/s, which corresponds to aHubble distance of 73.8 ± 5.3 Mly (22.62 ± 1.63 Mpc).[1] Additionally, 12non-redshift measurements give a distance of 67.21 ± 2.35 Mly (20.608 ± 0.721 Mpc).[2] It was discovered by German-British astronomerWilliam Herschel on 3 March 1786.[3] It was also observed byHeinrich d'Arrest on 15 March 1866, causing it to be listed twice in theNew General Catalogue, as NGC 4129 and as NGC 4130.[3]
