What star has a greater magnitude a Rigel or Sirius?
Sirius, which means that Rigel is brighter.
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.
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).
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
Does rigel have a greater magnitude than sirus?
No, which means that Rigel is brighter.

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.
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
Does rigel have a greater magnitude than sirus?
No, which means that Rigel is brighter.
What star whose magnitude of 0.1?
The nearest would be Rigel with an apparent magnitude of +0.12.
Even though this star has an absolute magnitude greater than that of sirius it looks dimmer from earth since its 100 times farther away?
Rigel has a greater absolute magnitude than Sirius but apears dimmer from Earth do to the farther distance the light waves must travel through space (just a little more information : ), but there are probably alot more stars around that distance
What is Orion's brightest star in the apparent magnitude?
Rigel is the brightest star in Orion and the sixth brightest star in the sky, with an apparent magnitude of 0.18.
Which is brighter Sirius or Rigel?
Sirius has a luminosity of: 25.4 while Rigel has a luminosity of: 66,000 Making Rigel brighter than Sirius.
How many times brighter is Capella than the sun?
Rigel has a luminosity of 66,000 times greater than our Sun.However, in apparent magnitude (Brightness) it has a magnitude of 0.18 whereas the Sun is -26.73.
Which star is bigger sirius or rigel?
Rigel is approximately ten times LARGER than Sirius
