NGC 2339 is a spiral galaxy in Gemini, 112 million light-years away
NGC 2339 is a spiral galaxy in the constellation Gemini , 112 million light-years away. It shines at magnitude 11.7 and spans 2.4′ × 1.5′ of sky, about 79,000 light-years across. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in February.
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.
