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.
Why does Rigel shine as brightly as Betelgeuse even though Rigel is much smaller?

What are the colors of Rigel and Betelgeuse?
Rigel is a blue-white star, while Betelgeuse is a red supergiant star.
Which is larger Rigel or Betelgeuse?
Betelgeuse is larger than Rigel. Betelgeuse is a red supergiant star with a diameter about 1,180 times that of the Sun, while Rigel is a blue supergiant with a diameter roughly 79 times that of the Sun.
Which star is brighter Betelgeuse or Rigel?
Rigel is brighter than Betelgeuse. Rigel is a blue supergiant star and one of the brightest stars in the night sky, while Betelgeuse is a red supergiant and although it is one of the largest stars known, it is not as bright as Rigel.
How big is Betelgeuse compared to Rigel?
Betelgeuse is larger in size than Rigel. Betelgeuse is a red supergiant star with a diameter about 800 times that of the Sun, while Rigel is a blue supergiant star with a diameter about 70 times that of the Sun.
Why is Rigel hotter than Betelgeuse?
Rigel is hotter than Betelgeuse because it is a young, massive star in the early stages of its life cycle, while Betelgeuse is an older, cooler, and more evolved star. The higher temperature of Rigel is due to the intense nuclear fusion reactions happening in its core, which generate more heat and energy compared to Betelgeuse.
Which is brighter Rigel or Betelgeuse?
Rigel is brighter than Betelgeuse. Rigel is a blue supergiant star that is one of the brightest stars in the night sky, while Betelgeuse is a red supergiant star that is dimmer in comparison.
Why does Rigel shine as bright as Betelgeuse even though Rigel is much smaller than Betelgeuse?
Rigel appears as bright as Betelgeuse because it is hotter and more luminous, even though it is smaller. The luminosity of a star depends on both its temperature and size, so a hotter, more luminous star can shine as brightly as a larger, cooler star.
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.
