Which is brighter Rigel or Betelgeuse?
Rigel is brighter.
What star is brighter Betelgeuse or Rigel?
Betelgeuse has an apparent magnitude of 0.42(v) and an absolute magnitude of -6.02. Rigel has an apparent magnitude of 0.12 and an absolute magnitude of -7.04. So Rigel is brighter.
The brightest star in a given constellation is designated as alpha?
Generally, true, but there are rare exceptions. For example, Betelgeuse is "Alpha Orionis" while Rigel, generally brighter then Betelgeuse, is "Beta Orionis". Betelgeuse is a somewhat variable star, and when the Bayer designations were assigned, Betelgeuse was the brighter star.
Which star is brighter Aldebaran or Betelgeuse?
Betelgeuse is brighter.
Why does Rigel shine just as brightly as Betelgeuse?
Even though Betelgeuse is much larger, Rigel is brighter due to its much higher temperature. Rigel is about 11,000 K and Betelgeuse is only about 3,500 K.
Is Betelgeuse hotter than Rigel?
No, Rigel is hotter. Rigel is a blue star with a temperature of about 11,000 K, and Betelgeuse is a red star with a temperature of about 3,500 K.

What type of stars are Betelgeuse and Rigel?

Which is brighter a beta star or gamma star?
Usually, the beta star. Stars are given names based on the constellation that they are in, with the brightest star in the constellation being "Alpha", the second brightest being "Beta, and the third-brightest being "Gamma" - and so on through the rest of the Greek alphabet. However, stars _can_ change their brightness. In the constellation Orion, the red supergiant star Betelgeuse was, in the 1600's when the stars were cataloged, the brightest star in Orion. So Betelgeuse was listed as "Alpha Orionis", while Rigel, a close second, was listed as "Beta Orionis". But Betelgeuse has been slimming down, perhaps beginning the collapse which will result in its destruction as a supernova. At any rate, Rigel is generally brighter than Betelgeuse this century. Not always; Betelgeuse is a variable star, and at its brightest, it is still brighter than Rigel.
