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.
What is the magnitude of Rigel?
Absolute magnitude: -7.84Apparent magnitude: +0.12
What is the absolute brightness of the Rigel?
The absolute magnitude is -7.92
How bright is Rigel?
Rigel is the brightest star in the constellation Orion.It has an apparent magnitude of 0.18 and an absolute magnitude of -6.7
What is the approximate absolute magnitude of Rigel?
-7.84 ± 0.2

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.
Why is Rigel appears brighter than aldeberan even though aldeberan is technically brighter than Rigel?
The absolute magnitude of Rigel is -7.92 while that of Aldebaran is -6.41. This means that Rigel is approx 4 times brighter than Aldebaran - technically. So the question is based on a flawed grasp of absolute magnitude.
Spica and Rigel have similar surface temperatures but their absolute magnitudes are different why is this?
Spica has a surface temperature of 22,400K and an absolute magnitude of -3.55Rigel has a surface temperature of 11,000K and an absolute magnitude of -6.7So the question is incorrect.
Does rigel have a greater magnitude than sirus?
No, which means that Rigel is brighter.
Even though this star has an absolute magnitude greater then that of sirius it looks dimmer from earth since it's 100 times farther away?
The apparent brightness of a star depends mainly on (1) its absolute (i.e., real) brightness, and (2) the square of its distance from us. The absolute magnitude of Sirius is +1.45, while that of Rigel is -6.95, meaning that Rigel is approximately 2,290 times as bright as Sirius. However, Rigel is approximately 100 times as far from us (870 light years versus 8.6 light years), which reduces its brightness relative to Sirius by a factor of over 10,000. This makes Sirius about 4.5 times brighter than Rigel for a difference of 1.62 magnitudes (-1.44 relative magnitude for Sirius versus +0.18 for Rigel).
What is the magnitude of the star Rigel?
-6.7
What star has a greater magnitude a Rigel or Sirius?
Sirius, which means that Rigel is brighter.
