Asterism Not Considered True Constellation
An asterism is a pattern of stars that are widely recognized and contained within an official constellation but is not counted as a true constellation in itself. The Big Dipper, for instance, is a famous asterism but the seven stars in this arrangement of stars represent less than half of the whole constellation known as Ursa Major. Another famous asterism is the three stars in a row that form Orion’s belt.
