NGC 4493 is an elliptical galaxy in Virgo, 308 million light-years away
NGC 4493 is an elliptical galaxy in the constellation Virgo , 308 million light-years away. It shines at magnitude 14.0 and spans 1.5′ × 44″ of sky, about 136,200 light-years across. It is faint: a 10-inch or larger telescope, or a camera, 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.
