NGC 621 is a lenticular galaxy in Triangulum
NGC 621 is a lenticular galaxy in the constellation Triangulum . It shines at magnitude 14.0 and spans 1.1′ × 1.1′. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in December.
Galaxy: a system of billions of stars, gas and dust held together by gravity, far outside the Milky Way. Spiral galaxies have a disk with arms; elliptical galaxies are smooth, round or oval swarms of older stars.
