NGC 4025 is a barred spiral galaxy in Ursa Major, 105 million light-years away
NGC 4025 is a barred spiral galaxy in the constellation Ursa Major , 105 million light-years away. It shines at magnitude 13.6 and spans 1.4′ × 55″ of sky, about 43,200 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.
