IC 4306 is an early spiral galaxy in Canes Venatici, 347 million light-years away
IC 4306 is an early spiral galaxy in the constellation Canes Venatici , 347 million light-years away. It shines at magnitude 15.0 and spans 1.1′ × 18″ of sky, about 111,000 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in 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.
