The Big Dipper is an asterism that makes up part of the constellation of Ursa Major (The Big Bear). It is seen here at the lower left of the image. The Little Dipper, part of the constellation of Ursa Minor (The Little Bear), is seen at the upper right. Polaris, the North Star, is at the end of the handle of the Little Dipper.
For example, the northern asterism known as the Big Dipper comprises the seven brightest stars in the IAU constellation (area) Ursa Major or the southern False Cross intersecting across the constellations of Carina and Vela.he term circumpolar constellation is used for any constellation that, from particular latitude on Earth, never sets below the horizon. From the North Pole or South Pole, all constellations north or south of the celestial equator are circumpolar constellations.
