The state flag of Alaska displays eight gold stars, forming the Big Dipper and Polaris, on a dark blue field. The Big Dipper is an asterism in the constellation Ursa Major, which symbolizes a bear, indigenous to Alaska. As depicted on the flag, its stars can be used as a guide by the novice to locate Polaris and determine true north.

The Big Dipper or the plough is a large asterism consisting of seven bright stars of the constellation Ursa Major; six of them are of second magnitude and one, Megrez (δ), of third magnitude. Four define a "bowl" or "body" and three define a "handle" or "head". It is recognized as a distinct grouping in many cultures. The North Star (Polaris), the current northern pole star and the tip of the handle of the Little Dipper, can be located by extending an imaginary line through the front two stars of the asterism, Merak (β) and Dubhe (α). This makes it useful in celestial navigation.
