NGC 2747 is a lenticular galaxy in Cancer, 166 million light-years away
NGC 2747 (PGC 025507) is a lenticular galaxy in the constellation Cancer, 166 million light-years away. It shines at magnitude 15.0 and spans 34″ × 21″ of sky, about 27,100 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 2747 from ε Leo
NGC 2747 lies 10.9° southwest of ε Leo, the magnitude 3.0 star. A fist held at arm's length covers about 10°.
NGC 2747 is highest in the evening in March
The chart gives its height above the horizon at 9 pm through the year, from 60°N to 40°S. It can be seen from the whole northern hemisphere and south to about 72°S, and never sets north of 72°N.
