Big Dipper

The Big Dipper (US) or the Plough (UK) is an asterism consisting of seven bright stars of the constellation Ursa Major; six of them are of second magnitude and one, Megrez (), 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.
