NGC 3689 is a mixed spiral galaxy in Leo, 149 million light-years away
NGC 3689 is a mixed spiral galaxy in the constellation Leo , 149 million light-years away. It shines at magnitude 12.3 and spans 1.5′ × 58″ of sky, about 64,000 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in April.
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.
