Rigel Star is the brightest star in the constellation of Orion. It is 800 light years from the Earth. Rigel is actually a three-star system consisting of the blue supergiant Rigel A and two distant, and dimmer stars. Rigel Star is 40,000 times brighter than the Sun. Rigel Star is only around 8 million years old. Over the next few million years, Rigel Star will expand into a red supergiant and it will explode as a supernova.
