IC 4187 is a lenticular galaxy in Canes Venatici, 465 million light-years away
IC 4187 is a lenticular galaxy in the constellation Canes Venatici , 465 million light-years away. It shines at magnitude 15.0 and spans 33″ × 24″ of sky, about 74,400 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.
