Plough(US Big Dipper) A group of stars in Ursa Major that contains the seven brightest stars in that constellation, nearly all with similar apparent magnitudes (mv ), and has a very distinctive shape (see illustration). The seven stars are Alioth, Dubhe, Alcaid, Mizar, Merak (mv : 2.36), Phecda (mv : 2.43), and Megrez (mv : 3.31), in order of brightness. Alcaid and Dubhe have different values and directions of proper motion than the other five so that the shape of the Plough is slowly but continuously changing.
