NGC 635 is a spiral galaxy in Cetus
NGC 635 is a spiral galaxy in the constellation Cetus . It shines at magnitude 15.0 and spans 36″ × 32″. 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.
