Which star is brighter Betelgeuse or Rigel?
Rigel is brighter than Betelgeuse.
What star has a greater magnitude a Rigel or Sirius?
Sirius, which means that Rigel is brighter.
Which is brighter larger stars or smaller stars?
Brightness is related to distance. However, from the same distance, an O class star is much much brighter than a M class star. As a comparison, an O class star would appear about 100,000 times brighter than our Sun, whereas a M class star could appear 0.0017 dimmer than our Sun, if the Sun was replaced with each star.
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.
Is there a star that is hotter than the sun?
Yes, many stars are brighter than our sun. Deneb and Rigel are two examples. Rigel is over 100,000 times brighter than Sol.
Which star is brighter Betelgeuse or Rigel?
Rigel is brighter than Betelgeuse.
The surface temperature of the star Rigel is about 15000celiusThe sun has a temperature of about 6000celius Why does the sun appear so much brighter?
The sun is a lot closer.
What star has a greater magnitude a Rigel or Sirius?
Sirius, which means that Rigel is brighter.

What does rigel have brighter then Sirius?
I'm not sure exactly what detail you want, but here's a start. Rigel is a triple star system. The main star of the three is a very luminous star. It is a blue supergiant star.
Is there a star that is hotter than the sun?
Yes, many stars are brighter than our sun. Deneb and Rigel are two examples. Rigel is over 100,000 times brighter than Sol.
Which star has the less absolute magnitude rigel or Sirius?
Sirius has less absolute magnitude than Rigel. Sirius is smaller and less luminous than Rigel, but much closer to us, so Sirius appears brighter. Sirius, in fact, is the brightest star in our sky (with the exception of our own star, the sun.) Rigel is still pretty bright, but many times farther away from us than Sirius.
Is Rigel your nearest star?
No. Proxima Centauri is the nearest star. Rigel is much further away.
Is a star brighter if it is closer to earth?
As star will appear brighter if it is closer to Earth, yes. How bright a star appears depend on how far away it is and the star's actual brightness.
Why does star Sirius appear brighter than star pollux?
While Pollux is actually brighter than Sirius, Sirius appears brighter because it is several times closer.
Is rigel a triple star binary star or single star?
Rigel is a triple star system.
