NGC 5087 is a 11.4 may bright Lenticular galaxy with active galaxies core from the Hubble type S0 in the constellation virgin on the ecliptic. It is estimated to be 78 million light years away from the Milky Way and about 60,000 light years in diameter. Together with four other galaxies, they form the small galaxy group LGG 345.
In the same area of the sky there is u. a. the galaxy NGC 5068 .
The object was discovered on April 8, 1788 by Wilhelm Herschel with an 18.7-inch reflector telescope , which she labeled “cF., vS., iF.” (Herschel's abbreviations for “considerably faint, very small, of an irregular figure ”).
