NGC 3628



NGC 3628

Description:

Spiral Galaxy NGC 3628 is located 35 million light years away from us in the constellation Leo.  This edge-on galaxy is part of the Leo Trio together with M65 & M66.  Because of the gravitaional "tug" from the other galaxies around it, the disk of this galaxy appears to be warped.  There is also an extremely faint tail of material to the left rim of the galaxy that appears to be orphan stars thrown off into space by a gravitational encounter.
