The Big Dipper is located near the north celestial pole (almost the exact location of the North Star) and is circumpolar in most of the northern hemisphere beginning at 41degrees N. latitude (the latitude of New York City), and all latitudes farther north, meaning it does not sink below the horizon at night.
The constellation Ursa Major contains the group of stars commonly called the Big Dipper. The handle of the Dipper is the Great Bear's tail and the Dipper's cup is the Bear's flank.The Big Dipper is not a constellation itself, but an asterism, which is a distinctive group of stars.Another famous asterism is the Little Dipper in the constellation Ursa Minor.he constellation is low in the sky in autumn evening sky, so it was said that the hunters had injured the bear and its blood caused the trees to change color to red. Although the whole of Ursa Major is difficult to see without very dark skies, the Big Dipper is one of the most recognizable patterns in the northern sky.
