IC 4331 is a barred spiral galaxy in Bootes
IC 4331 (PGC 1727130) is a barred spiral galaxy in the constellation Bootes . It shines at magnitude 15.0 and spans 38″ × 30″. 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.
