NGC 3628 - Hamburger Galaxy

Show astrometry data

NGC 3628, named the Hamburger Galaxy, is an unbarred spiral galaxy in the constellation Leo, approximately 35 million light years from Earth. Along with Messier galaxies M 65 and M 66, it forms the Leo Triplet, a small galaxy group. It derives its name from its appearance, with a puffy bulging galactic disk obscured by dark dust lanes. The galaxy's tidal tail (upper left) resulting from interaction with another galaxy may be up to 300,000 light years long.
