NGC 7720A is an elliptical galaxy in Pegasus, 403 million light-years away
NGC 7720A (PGC 085570) is an elliptical galaxy in the constellation Pegasus , 403 million light-years away. It shines at magnitude 13.0 and spans 41″ of sky, about 79,700 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in November.
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.
