IC 4458 is a spiral galaxy in Centaurus
IC 4458 (ESO 327-003) is a spiral galaxy in the constellation Centaurus . It shines at magnitude 17.0 and spans 35″ × 12″. 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.
