Which star is brighter Aldebaran or Betelgeuse?
Betelgeuse is brighter.
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.
Which is brighter Aldebaran or Betelgeuse?
This could be considered a trick question. Generally, Betelgeuse is brighter BUT Betelgeuse is what we call a variable star and there are times when it is fainter than Aldebaran.
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.
Which star is brighter Vega or Betelgeuse?
Brightnest is a factor of luminousity and distance as seen from Earth. (Apparent magnitude)Vega - 0.03.Betelgeuse: 0.42So Betelgeuse is brighter as viewed from Earth.

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.
Can Betelgeuse be seen with the human eye?
Yes, Betelgeuse is one of the brighter stars in the sky. The red star of Orion's left shoulder is Betelgeuse.
Does our sun have a lower absolute magnitude then Betelgeuse?
No, Betelgeuse has a lower absolute magnitude compared to the Sun. Betelgeuse is a red supergiant star with a much larger luminosity, making it appear brighter despite its greater distance from Earth.
Is aldeberan a giant star?
Yes.
Why is Jupiter in the night sky brighter than betelgeuse?
Jupiter appears brighter in the night sky than Betelgeuse because it is closer to Earth and reflects more sunlight due to its atmosphere. Betelgeuse, on the other hand, is a red supergiant star that emits its own light, which can make it appear dimmer in comparison.
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.
Does the absolute magnitude of the sun show that it is the brightest star?
No. The sun has an absolute magnitude of 4.83. By comparison, Betelgeuse has an absolute magnitude of -5.85. Lower numbers indicate a brighter star. In this case Betelgeuse is actually several thousand times brighter than the sun. The sun is the brightest star as measure by apparent magnitude, which is how bright a star looks from a given location and depends on both absolute magnitude and distance.
