Is Betelgeuse one of the 20 brightest stars?
Betelgeuse varies in brightness a bit, but it's around #8 in brightness.
What is the absolute brightness of Betelgeuse?
-6.02
Is Vega or Betelgeuse the brightest star?
Brightness is a function of a stars luminosity as observed from Earth. So our Sun is the brightest. Vega has an apparent magnitude of: 0.03 Betelgeuse has an apparent magnitude of 0.42 So, in apparent magnitude, Vega is brighter.
Why does Rigel have the designation beta Ori when it is a brighter star than Betelgeuse?
Answer When Bayer prepared his catalogue, there was no way to measure stellar brightness precisely. Traditionally, the stars were assigned to one of six magnitude classes, and Bayer's catalog lists all the first-magnitude stars, followed by all the second-magnitude stars, and so on. However within each magnitude class, there was no attempt to arrange stars by relative brightness. For example, in the Orion constellation, Bayer first designated the two 1st-magnitude stars, Betelgeuse and Rigel, as Alpha and Beta, with Betelgeuse (the shoulder) coming ahead of Rigel (the foot), even though the latter is the brighter.Also worth mentioningis that Betelgeuse is a semiregular variable star, and sometimes IS brighter than Rigel.So, it is possible that Betelgeuse was mistakenly classified as the brightest because it could have been experiencing an increase in brightness at that time.
