Polaris is located in the constellation of Ursa Minor, the Little Bear. It sometimes also goes by the name âStella Polaris.â The seven stars from which we derive a bear are also known as the Little Dipper.

Polaris science. The single point of light that we see as Polaris is actually a triple star system, or three stars orbiting a common center of mass. The primary star, Polaris A, is a supergiant with about six times the mass of our sun. A close companion, Polaris Ab, orbits 2 billion miles from Polaris. Much farther away, near the top of the illustration at right, is the third companion Polaris B. Polaris B is located approximately 240 billion miles from Polaris A.
