Quick Summary

Diagram showing the seven main stars of the Big Dipper-Merak, Dubhe, Phecda, Mizar, Alkaid, Alioth, and Megrez-labeled with their names and distances from Earth in light-years, with lines connecting each star to Earth and a blue plane illustrating the constellation's apparent shape as seen from 50 light-years away.
Although the stars of the Big Dipper seem to belong together, they are actually widely separated. A person looking at the Big Dipper stars from a position in space different from that of Earth would see them in a different shape, or they might seem completely unrelated to each other in the sky.

Dubhe is a star system that is the second brightest component of the constellation Ursa Major. It is also known as Alpha Ursae Majoris. Dubhe is one of the two stars in the cup of the Big Dipper, along with Merak, that are known as the "pointer stars" because they can be used to locate Polaris, the North Star. While visible as a single star to the naked eye, Dubhe is actually a system of four stars gravitationally bound together. It is the brightest star in Ursa Major, with a magnitude of 1.8.12
