What is the magnitude of Rigel?
Rigel has an apparent magnitude of around 0.12, making it one of the brightest stars in the sky. Its absolute magnitude, which measures intrinsic brightness, is around -7.0, indicating its high luminosity.
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?
Yes, the star with the higher absolute magnitude will appear dimmer from Earth if it is located farther away. This is because brightness decreases with distance due to the inverse square law of light, meaning that a star will appear dimmer the farther it is from the observer.
What is absolute magnitude of Rigel?
Its absolute magnitude is -7.92
What is the approximate absolute magnitude of Rigel?
The approximate absolute magnitude of Rigel is about -7.0. This makes it one of the brightest stars in the night sky.
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 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.
Which star has the less absolute magnitude rigel or Sirius?
Sirius has a lower absolute magnitude than Rigel. Sirius is one of the brightest stars in the sky with an absolute magnitude of 1.42, while Rigel has an absolute magnitude of -8.1, making it much brighter 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.
What does the absolute brightness of the star depend on?
the brightness of a star
A star's brightness as if it were a standard distance is called?
Absolute Brightness .
What might influence absolute brightness?
If you mean infinite brightness, then nothing.
What variable of apparent brightness is eliminated when discussing absolute brightness?
The variable of distance is eliminated when discussing absolute brightness. Absolute brightness specifically refers to the inherent brightness of an astronomical object without the influence of its distance from the observer.
Even though this star has an absolute magnitude greater than that of sirius it looks dimmer from earth since its 100 times farther away?
The star's absolute magnitude is a measure of its intrinsic brightness. Sirius appears brighter from Earth than a star with a greater absolute magnitude because Sirius is closer to us, which affects its apparent brightness. The star with the greater absolute magnitude might be intrinsically brighter but is much farther away, leading to its fainter appearance from Earth.
