NGC 7454 is an elliptical galaxy in Pegasus, 77 million light-years away
NGC 7454 is an elliptical galaxy in the constellation Pegasus , 77 million light-years away. It shines at magnitude 11.8 and spans 1.5′ × 45″ of sky, about 34,400 light-years across. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in October.
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.
