||M 100, NGC 4321
||Sc type spiral galaxy
||12h23m, + 15°49'
||Coma Berenices (Com)
||M100, although situated in
constellation Coma Berenices, is one of the brightest spiral members of the
Virgo Cluster of galaxies. Unlike the nearby
spiral M99 , it rotates counter clockwise.
M100 floats at a distance of 60
million light years from earth. It is suspected that much of
its mass is situated in low density exterior regions that do not readily
show up in photographs. The rightmost of the three lenticular
galaxies towards the bottom and right is NGC 4328 (mag 14.3).
It shows a faint jet.
There is also a wide field image
taken with a 6" refractor telescope.
