NGC 2743

NGC 2743 is a late spiral galaxy in Cancer, 105 million light-years away

NGC 2743 is a late spiral galaxy in the constellation Cancer, 105 million light-years away. It shines at magnitude 14.0 and spans 1.1′ × 45″ of sky, about 33,500 light-years across. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in March.

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 2743 from ε Leo

NGC 2743 lies 9.4° west of ε Leo, the magnitude 3.0 star. A fist held at arm's length covers about 10°.
