How many stars make up the Big Dipper?


Quick Answer

The Big Dipper forms from seven stars: Alkaid, Mizar, Alioth, Megrez, Phad, Merak and Dubhe. The stars in the Big Dipper appear in skies over the Northern Hemisphere, arranging in a distinct pattern that forms the handle and bowl of the Dipper. In addition to forming the Big Dipper, these stars point toward Polaris, the North Star, providing a sense of direction and orientation.

As with constellations and stars in the sky, the position of the Big Dipper in the sky changes throughout the year. In the warmer months of spring and summer, the Big Dipper appears high in the sky and shines brightest. During the colder months of fall and winter, it shines less brightly and hovers just above the horizon line. Even at its lowest point in the winter sky, the Big Dipper remains circumpolar, meaning none of its points dip below the horizon line.

This unique arrangement of stars contains seven major stars, which derive their names from different origins, including Arabic and Latin. Its two most prominent stars include Alkaid, which forms the tip of its handle and Dubhe, which extends farthest from Alkaid. Dubhe, in Arabic, translates to "Great Bear." Dubhe classifies as a pointer star, along with nearby Merzak. These two stars lead to Polaris, the North Star, and to Regulus, a star in the constellation Leo.
