Rigel (pronounced ) (Î² Orionis) is the brightest star in the constellation Orion and the seventh brightest star in the sky, with visual magnitude 0.12. Although it has the Bayer designation "beta", it is almost always brighter than Alpha Orionis (Betelgeuse). It also has the alternative traditional names Algebar or Elgebar, but these are almost never used.
Rigel is the name of an Argentinian sounding rocket. The double stage Rigel (first stage Canopus, second stage Orion-2) was launched seven times between 1969 and 1973. The Rigel rocket has a maximum altitude of 310 km, a launch mass of 300 kg, a diameter of 0.228 metres and a length of 6.30 metres.
The Rigel was a Norwegian vessel named after the brightest star in the Orion constellation, built in Copenhagen, Denmark in 1924. The vessel was sunk by the British Royal Navy off Norway on 27 November 1944 during World War II.
