NGC 5523 is a mixed spiral galaxy in Bootes, 66 million light-years away
NGC 5523 is a mixed spiral galaxy in the constellation Bootes, 66 million light-years away. It shines at magnitude 13.0 and spans 2′ × 53″ of sky, about 39,200 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in 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.
Finding NGC 5523 from Arcturus
NGC 5523 lies 6.1° north of Arcturus, the magnitude -0.1 star. Three fingers held at arm's length cover about 5°.
NGC 5523 is highest in the evening in June
The chart gives its height above the horizon at 9 pm through the year, from 60°N to 40°S. It can be seen from the whole northern hemisphere and south to about 65°S, and never sets north of 65°N.
