IC 4122 is a lenticular galaxy in Coma Berenices, 764 million light-years away
IC 4122 (PGC 045092) is a lenticular galaxy in the constellation Coma Berenices , 764 million light-years away. It shines at magnitude 14.1 and spans 50″ × 36″ of sky, about 186,700 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in 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.
