Illustration of a view from within the Polaris triple star system. The North Star, Polaris A (bottom) is a bright supergiant variable star. Just above Polaris is a small companion, Polaris Ab, which is about 3.2 billion kilometres from Polaris. Much farther away, near the top of the illustration, is the wide companion Polaris B. Polaris B is located approximately 386 billion kilometres from Polaris A. The two companion stars are the same temperature as Polaris A, but are dwarf stars. | |
