However, 25 non-redshift measurements give a much closer mean distance of . It was discovered by British astronomer James Dunlop on 7 May 1826.
NGC 4696 is the brightest galaxy in the Centaurus Cluster, a large, rich cluster of galaxies in the constellation of the same name. The galaxy is surrounded by many dwarf elliptical galaxies also located within the cluster. There is believed to be a supermassive black hole at the center of the galaxy.
Supernova One supernova has been observed in NGC 4696: (Type Ia, mag. 17.2078) was discovered by the Distance Less Than 40 Mpc Survey (DLT40) on 28 May 2017.
