* Ursa Major is a prominent constellation in the Northern Hemisphere.
* The Big Dipper, which is often mistaken for the entire constellation, is actually an asterism (a recognizable pattern of stars) within Ursa Major.
* The Big Dipper's shape resembles a dipper, or a wagon, with its four stars forming the body of the dipper/wagon and the three stars forming the handle.
While Ursa Major isn't a star cluster (a group of stars physically close together), the Big Dipper's stars are all part of the same constellation, and it's a familiar pattern in the night sky.
