NGC 4157 is a mixed spiral galaxy in Ursa Major, 54 million light-years away
NGC 4157 is a mixed spiral galaxy in the constellation Ursa Major , 54 million light-years away. It shines at magnitude 11.2 and spans 6.2′ × 1.1′ of sky, about 97,200 light-years across. It is a telescope object, 6 inches or larger, 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.
