WebFar out along one spiral arm there gleams the star we call our Sun. It is, we think, an average star of middle age and middle size, much like hundreds of thousands of its distant neighbors. It belongs to a common class of stars called dwarfs, to distinguish them from giant red stars like Antares and Betelgeuse, whose diameters would stretch across 500 … WebAccording to NASA, Space Exploration and Astronomy News Rigel is 863 light years away. Betelgeuse is almost in the same direction but only 548 light-years away but that is uncertain by as much as 100 light-years because Betelgeuse is a pulsating star getting brighter and dimmer. But a good guess is that it is another 315 light years to Rigel.
