NGC 4456 is a spiral galaxy in Hydra, 248 million light-years away
NGC 4456 (ESO 441-030) is a spiral galaxy in the constellation Hydra , 248 million light-years away. It shines at magnitude 14.0 and spans 1.3′ × 41″ of sky, about 93,000 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in May.
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.
