IC 1145 is a spiral galaxy in Ursa Minor, 303 million light-years away
IC 1145 is a spiral galaxy in the constellation Ursa Minor , 303 million light-years away. It shines at magnitude 15.0 and spans 1.5′ × 24″ of sky, about 128,000 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in July.
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.
