IC 4099 is an elliptical galaxy in Coma Berenices

IC 4099 (LEDA 1698322) is an elliptical galaxy in the constellation Coma Berenices. It shines at magnitude 16.0 and spans 39″ × 24″. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in May.

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.
