The movement of the Plough

Some stars never set these are called circumpolar stars and the constellations which they are in are called circumpolar constellations. The constellation Ursa Major (the Plough) is a circumpolar constellation. You can always see it (from the Northern Hemisphere).
The animation shows you how the Plough moves round the Pole Star (Polaris). It takes just under one day to make a complete revolution.
