NGC 587 is a mixed spiral galaxy in Triangulum, 221 million light-years away
NGC 587 is a mixed spiral galaxy in the constellation Triangulum , 221 million light-years away. It shines at magnitude 13.0 and spans 2.2′ × 40″ of sky, about 143,200 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in November.
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.
