IC 4457 is a spiral galaxy in Bootes
IC 4457 (PGC 1553586) is a spiral galaxy in the constellation Bootes . It shines at magnitude 16.0 and spans 28″ × 18″. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in June.
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.
