M85 is the northernmost member of the Virgo Cluster in Messier's catalog, and thus situated in constellation Coma Berenices. It is a luminous lenticular (S0) galaxy; in many respects it seems to be a twin of M84. It seems to consist of an old yellow stellar population only. In our photo, the elliptical area covered by M85 has an apparent major axis of 4 to 5 arc minutes, but on longer exposures its angular dimension is about 7.1x5.2 arc minutes. This implies that the luminous disk of this galaxy has a linear diameter of about 125,000 light years.
M85 is left in our image; on the right hand side the small barred spiral NGC 4394 is visible, which is of mag 11.2 and looks like a hazy star. The separation of the centers of these galaxies is about 8 minutes of arc. As both galaxies are receding at about 700 km/sec, they may form a physical pair.
The type I supernova 1960R appeared in M85 on Dec 20, 1960 and reached mag 11.7. Supernova hunters should take care not to be fooled by the foreground star SSE of this galaxy's nucleus !
Messier observed M85 on March 18th, 1781 "Nebula without a star in Virgo, on the same parallel as number 84 above, and very close to it. They have the same appearance and both appear in the same telescopic field." Charles Messier from his catalogue
