s 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 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.
The distance to NGC 4697 is not known with high precision: measurements vary from 28 to 76 million light-years. According to the NASA Extra-galactic Database, the average is about 38 million light-years; according to SIMBAD, about 50 million light-years.
Elliptical galaxy
An elliptical galaxy is a galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile. They range in shape from nearly spherical to highly flat and in size from hundreds of millions to over one trillion stars...
