IC 4351 is a spiral galaxy in Hydra, 95 million light-years away
IC 4351 (ESO 445-084) is a spiral galaxy in the constellation Hydra , 95 million light-years away. It shines at magnitude 11.6 and spans 6.6′ × 1′ of sky, about 180,100 light-years across. It is a telescope object, 6 inches or larger, 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.
