Galaxy in the constellation Centaurus
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]
