The star as seen from Earth is actually a triple star system, with the primary star a blue-white supergiant of absolute magnitude −7.84 and around 130,000 times as luminous as the Sun. An Alpha Cygni variable, it pulsates periodically. Visible in small telescopes, Rigel B is itself a spectroscopic binary system, consisting of two main sequence blue-white stars of spectral type B9.The above text is a snippet from Wikipedia: Rigel
