Messier 86 (also known as NGC 4406) is an 8.9 mag bright lens-shaped galaxy with an area of 8.9 '× 5.8' in the constellation Virgo .
M86 is located in the center of the Virgo galaxy cluster in the vicinity of the giant galaxy M87 . In the past, their type was given in the Hubble sequence as E3 (elliptically flattened), but modern authors tend to indicate the lens-shaped type S0. The galaxy is particularly noticeable in the galaxy cluster due to its high blue shift . The galaxy is approaching our Milky Way at over 400 km / s, which results in a pecular velocity of over 1700 km / s compared to the center of gravity of the galaxy cluster, one of the highest pecular velocities in the Virgo cluster.
M86 belongs to the so-called Markaryan chain , a group of galaxies in an area about 1.5 degrees in diameter.
discovery
The galaxy NGC 4406 was first discovered by Johann Köhler on May 5, 1779 and rediscovered on March 18, 1781 by the French astronomer Charles Messier .
