NGC 4647 is a mixed spiral galaxy in Virgo, 53 million light-years away
NGC 4647 is a mixed spiral galaxy in the constellation Virgo , 53 million light-years away. It shines at magnitude 11.6 and spans 2.8′ × 2.4′ of sky, about 42,600 light-years across. It is a telescope object, 6 inches or larger, 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.
