NGC 845 is a spiral galaxy in Andromeda, 143 million light-years away
NGC 845 is a spiral galaxy in the constellation Andromeda , 143 million light-years away. It shines at magnitude 13.4 and spans 1.6′ × 20″ of sky, about 67,600 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in December.
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.
