NotesM59 is an elliptical galaxy, but one in which the elliptical form is compressed and flattened somewhat. Its bright core contains a supermassive black hole, and the galaxy is notable for its extensive halo of globular clusters, with more than two thousand such clusters orbiting around the main galaxy.

M59 is part of a swarm of galaxies that straddle the border between Virgo and Coma Berenices. M59 itself lies on the Virgo side of the border, and is a galaxy of elliptical form.
