IC 4305 is a lenticular galaxy in Canes Venatici, 407 million light-years away
IC 4305 is a lenticular galaxy in the constellation Canes Venatici , 407 million light-years away. It shines at magnitude 14.0 and spans 59″ × 48″ of sky, about 115,900 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in June.
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.
