In stellar navigation, Rigel is one of the most important navigation stars, since it is bright, easily located and equatorial, which means it is visible all around the world's oceans (the exception, areas within 8Â° of the North Pole).
Rigel is a blue-white star and, we know from experiments done in the lab, that its surface gases must be over 12,000 o C to give it that (peak) color. At the other extreme is Betelgeuse. Its deep red color shows it has a surface temperature of only 3400 o C. Aldebaran is slightly warmer than Betelgeuse, around 4000 o C, so it is more orange than red. We can use this nice color scheme to estimate the surface temperature of stars.
