NGC 3842 is an elliptical galaxy (E) in Leo, 280 million light-years away
NGC 3842 (UGC 6704, PGC 36487) is an elliptical galaxy (E) in the constellation Leo , 280 million light-years away. It shines at magnitude 11.8 and spans 2.1′ × 1.5′ of sky, about 174,300 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.
