IC 4393 is a late spiral galaxy in Centaurus, 132 million light-years away
IC 4393 (ESO 446-044) is a late spiral galaxy in the constellation Centaurus , 132 million light-years away. It shines at magnitude 13.7 and spans 2.3′ × 18″ of sky, about 88,600 light-years across. 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.
