NGC 1637 is a late spiral galaxy in Eridanus, 47 million light-years away
NGC 1637 is a late spiral galaxy in the constellation Eridanus , 47 million light-years away. It shines at magnitude 10.8 and spans 3.2′ × 2.7′ of sky, about 43,600 light-years across. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in January.
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.
