Intro and Visual description
Ursa Major or the Big Bear is the third largest of the 88 constellations. Seven stars form a familiar group of stars, or an "asterism" within the constellation. In America they are called the "Big Dipper" or "Drinking Gourd," and in Britain the "Plough" or the "Wain." The Big Dipper is one of the most easily recognizable groups of stars in the sky. It is referred to as circumpolar because it never completely sets below the horizon, but is visible in northern skies year-round.
