Why does Rigel shine just as brightly as Betelgeuse?
Rigel appears as bright as Betelgeuse even though it is further away because Rigel is intrinsically brighter (has a higher luminosity) than Betelgeuse. Despite being further away, its higher luminosity compensates for the distance, making it appear similarly bright in the sky.
Which is larger Rigel or Betelgeuse?

What are Betelgeuse and Rigel?
Betelgeuse and Rigel are both bright stars in the constellation of Orion. Betelgeuse is a red supergiant star nearing the end of its life, while Rigel is a blue supergiant star. Betelgeuse is one of the largest stars known, and its brightness can vary significantly over time. Rigel, on the other hand, is a very luminous star and is actually a multiple star system, with several companion stars orbiting around it.
Why are the stars Betelgeuse and Rigel also known as alpha and beta Orionis?
Betelgeuse and Rigel are brighter and more prominent stars in the constellation Orion. In the Bayer classification system, which names stars using Greek letters in order of apparent brightness within a constellation, Betelgeuse is designated as Alpha Orionis and Rigel as Beta Orionis based on their brightness ranking within Orion.
Why does rigel shine as brightly as betelgeuse even though rigel is much smaller than betelgeuse?
Rigel appears as bright as Betelgeuse because it is closer to Earth than Betelgeuse, even though Rigel is smaller and less luminous. The brightness of a star is determined by both its luminosity and distance from Earth, so a smaller, closer star can appear just as bright as a larger, more distant one.
