NGC 7623 is a lenticular galaxy in Pegasus, 172 million light-years away
NGC 7623 is a lenticular galaxy in the constellation Pegasus , 172 million light-years away. It shines at magnitude 12.8 and spans 1.3′ × 57″ of sky, about 67,000 light-years across. It is faint: a 10-inch or larger telescope, or a camera, 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.
