NGC 3338 is a late spiral galaxy in Leo, 75 million light-years away
NGC 3338 is a late spiral galaxy in the constellation Leo , 75 million light-years away. It shines at magnitude 10.8 and spans 1.2′ × 43″ of sky, about 26,800 light-years across. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in April.
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.
