NGC 4697 (also known as Caldwell 52) is an elliptical galaxy some 40 to 50 million light-years away in the constellation Virgo. It is a member of the NGC 4697 Group, a group of galaxies also containing NGC 4731 and several generally much smaller galaxies.[3] This group is about 55 million light-years away; it is one of the many Virgo II Groups, which form a southern extension of the Virgo Supercluster of galaxies.[3]

The distance to NGC 4697 is not known with high precision: measurements vary from 28 to 76 million light-years.[1] According to the NASA Extra-galactic Database, the average is about 38 million light-years;[1] according to SIMBAD, about 50 million light-years.[2]

The supermassive black hole at the core of NGC 4697 has a mass of 1.3+0.18
−0.17
×108 M
as measured from Atacama Large Millimeter Array observations of the rotation of the central gas disk.[4]

One supernova has been observed in NGC 4697: SN 2018imd (type Ia, mag. 15.5).[5]
