NGC 3628 is an unbarred spiral galaxy about
35 million light-years away in the constellation Leo. It has an
approximately 300,000 light-years long tidal tail. NGC 3628
along with M65 and M66 form the famous Leo Triplet, a small
group of galaxies. Its most conspicuous feature is the broad and
obscuring band of dust located along the outer edge of its
spiral arms, effectively transecting the galaxy to our view.
