NGC 4018 is an early spiral galaxy in Coma Berenices, 178 million light-years away
NGC 4018 is an early spiral galaxy in the constellation Coma Berenices , 178 million light-years away. It shines at magnitude 13.8 and spans 1.4′ × 25″ of sky, about 71,900 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.
