NGC 4697 Observation data (J2000 epoch) Constellation Virgo Right ascension 12h 48m 35.9s[1] Declination -05° 48′ 03″[1] Redshift 1241 ± 1 km/s[1] Distance ~ 38 Mly[1] / ~ 50 Mly[2] Type E6[1] Apparent dimensions (V) 4′.4 × 2′.8[2] Apparent magnitude (V) 10.97[1] Other designations Caldwell 52 See also: Galaxy, List of galaxies 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]
