M 85 - Lenticular (S0) Galaxy M85 (NGC 4382), type S0, in Coma Berenices

RA 12 : 25.4 (h:m); DEC +18 : 11 (deg:m); Distance 60 million light years;
Visual Brightness 9.1 (mag); Apparent Dimension 7.1x5.2 (arc min).

M85 is the northernmost member of the Virgo Cluster in Messier's catalog, and thus situated in constellation Coma Berenices; the luminous disk of this galaxy has a linear diameter of about 125,000 light years.

M85 is right in my image [North is up]; on the left 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 centres 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.
