Betelgeuse and Rigel are exceptionally bright stars due to their intrinsic luminosity, which is a measure of the total amount of energy they emit. Both are massive stars in later stages of their evolution, with Betelgeuse being a red supergiant and Rigel a blue supergiant, leading to their high brightness. Despite their great distances from Earth—approximately 640 light-years for Betelgeuse and about 860 light-years for Rigel—their vast energy output makes them appear prominent in our night sky. Their brightness is a combination of their size, temperature, and the intense energy they produce.

Betelgeuse is the brightest star in the constellation Orion However Betelgeuse is a cool red star that is 520 light years from Earth How can Betelgeuse look so bright if it is that far away?
It isn't the brightest star - at least, usually Rigel is brighter. However, Betelgeuse is variable, and can sometimes be brighter than Rigel. Wikipedia lists its luminosity as 105,000 times the luminosity of our Sun; and the distance, as 640 light years. Assuming these numbers, this would make it as bright as a star that is 10.5 times as bright as our Sun, at a distance of only 6.4 light years. In other words, the extreme luminosity compensates for its distance.
