NGC 3605 is an elliptical galaxy in Leo, 65 million light-years away
NGC 3605 is an elliptical galaxy in the constellation Leo , 65 million light-years away. It shines at magnitude 12.3 and spans 1.3′ × 43″ of sky, about 23,700 light-years across. It is faint: a 10-inch or larger telescope, or a camera, 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.
