The Leo Triplet is a small group of spiral galaxies in the northern constelleation Leo including M66, M65 and NGC 3628 the Hamburger Galaxy. The group is also called the M66 Group and lies at an approximate distance of 30 million light years from Earth. From Earth the galactic disks are seen at different angles. NGC 3628 appears edge-on, while M65 and M66 are inclined so that their spiral arms become visible. Gravitational interactions between galaxies in the group have also left telltale signs, including the warped and inflated disk of NGC 3628 and the drawn out spiral arms of M66.
