What group of stars comprise the constellation Ursa Major?
Stars are scattered randomly across the sky. Apart from the rare exceptions, the stars that make up constellations have absolutely nothing to do with each other except that they're close to the same direction from the solar system. The stars which make up the Big Dipper are actually hundreds of light years away from each other. They just look like they are close together, because the naked eye cannot discern the actual magnitude or distance.
The stars that make up this constellation are: Merak, Dubhe, Megrez, Mizar, Alioth, Al Caid, Al Cor.
