NGC 4709 is an elliptical galaxy[3] located in the constellation Centaurus.[4] It is considered to be a member of the Centaurus Cluster[5][6] and is the dominant member of a small group of galaxies known as "Cen 45"[7] which is currently merging with the main Centaurus Cluster (Cen 30)[8] even though the two subclusters' line of sight redshift velocities differ by about 1500 km/s.[9] NGC 4709 was discovered by astronomer James Dunlop on May 7, 1826.[10]

Distance estimates

Lucey et al. suggests that NGC 4709 and the Cen 45 subgroup lie at about the same distance as the main Centaurus Cluster[11][8] which is about 150 Mly (45 Mpc).[2]
