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.
