Rigel is an intrinsic variable star with an apparent magnitude ranging from 0.05 to 0.18. It is typically the seventh-brightest star in the celestial sphere, excluding the Sun, although occasionally fainter than Betelgeuse. It is fainter than Capella, which may also vary slightly in brightness. Rigel appears slightly blue-white and has a B-V color index of −0.06. It contrasts strongly with reddish Betelgeuse. WebEach star is assigned a spectral type based on the appearance of its spectrum. Stellar classes typically have three elements: a letter (O-B-A-F-G-K-M), an Arabic number between 0 and 9, and a Roman number between I and VII (or a zero). The letter indicates the spectral class, which is determined based on the star’s effective temperature.
