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.
Since the Big Dipper is part of the constellation Ursa Major (The Great Bear), it is technically not a constellation. It's what is called an asterism, which is the name given to interesting star patterns that are easily recognizable, but not one of the official constellations.he Big Dipper is no exception as you can use two of the stars in its cup to find the North Star and you can use the arc of its handle to find the giant red star Arcturus.
