IC 4103 is a spiral galaxy in Canes Venatici
IC 4103 is a spiral galaxy in the constellation Canes Venatici . It shines at magnitude 15.0 and spans 46″ × 30″. 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.
