IC 4316 is a barred irregular galaxy in Hydra, 14 million light-years away
IC 4316 (ESO 445-006, ESO-LV 445-0060) is a barred irregular galaxy in the constellation Hydra , 14 million light-years away. It shines at magnitude 13.9 and spans 1.4′ × 1′ of sky, about 5,540 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.
