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]
