The two brighter components, called A and B, about 0.2 light-year farther from the Sun, revolve around each other with a period of about 80 years, while Proxima circles them with a period of 550,000 years.
Algol wins notoriety for its wild swings in brightness, which recur with clock-like precision.
The third star in the system (Ab) is a magnitude 2.3 A-type star that is separated from the primary pair by a distance of 2.96 AU, giving the system a mutual orbital period of 681 days.
