NGC 7255 is an early spiral galaxy in Aquarius, 204 million light-years away
NGC 7255 is an early spiral galaxy in the constellation Aquarius , 204 million light-years away. It shines at magnitude 15.0 and spans 1.5′ × 19″ of sky, about 87,300 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in October.
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.
