Galaxies of the Virgo Cluster

The Virgo Cluster is extremely rich in member galaxies, with over 2000 large and small members. While most of them are very small and can only be detected with huge telescopes, there is still a very large number of promising targets for amateur astronomers, even with small telescopes, starting at 2 or 3 inch, or even binoculars; this fact is suggested already by the fact that Messier's catalog list 16 Virgo cluster members: M49, M58, M59, M60, M61, M84, M85, M86, M87, M88, M89, M90, M91, M98, M99, and M100.

Because of the huge gravity caused by the galaxy cluster's enormous mass, some of the Virgo Cluster members have been accelerated to high peculiar velocities, with respect to the cluster's center of mass, at least up to 1,600 km/sec. As the cluster is receding from us at only 1,100 km/sec, some of its members are moving toward us at considerably high blueshift rates, the highest measured for any extragalactic objects. Others happen to move into the direction away from us, and are thus receding at more than souble the velocity as the cluster. In the following, a list is given of extreme peculiar motions of Virgo Cluster member galaxies (from the Sky Catalog 2000); we give the radial velocity with respect to our Milky Way's Galactic Center:

Toward us:

   IC 3258                    -517 km/s
   M86 (NGC 4406)             -419
   M90 (NGC 4569)             -383
   NGC 4419                   -342
   NGC 4318                   -300
   M98 (NGC 4192)             -220

Away from us:

   NGC 4388                  +2535 km/s
   IC 3453                   +2489
   NGC 4607                  +2367
   NGC 4168                  +2342
   M99 (NGC 4254)            +2324
   NGC 4354                  +2305

Below we give a table of more Virgo Cluster galaxies, ordered by Right Ascension; the selection includes most galaxies brighter than about 11 mag visually, plus some remarkable galaxies:
