The lenticular ( Hubble-type S0) galaxy M 85 is the northernmost galaxy of the Virgo galaxy cluster . The bar-spiral galaxy NGC 4394 with a magnitude of 11.2 mag, which can be found at a distance of 8  arc minutes , seems to be a real companion of M85, because both galaxies show the same redshift , which corresponds to a radial velocity of approx. 700 km / s.

On December 20, 1960, the type Ia supernova SN 1960R was discovered in Messier 85 .
