NGC 7743 is a lenticular galaxy in Pegasus, 66 million light-years away
NGC 7743 is a lenticular galaxy in the constellation Pegasus , 66 million light-years away. It shines at magnitude 12.4 and spans 2.6′ × 2.2′ of sky, about 50,200 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in 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.
