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