Brightnest is a factor of luminousity and distance as seen from Earth. (Apparent magnitude)
- Vega - 0.03.
- Betelgeuse: 0.42
So Betelgeuse is brighter as viewed from Earth.

Which star is brighter Aldebaran or Betelgeuse?
Betelgeuse is brighter.
Is Vega or Betelgeuse the brightest star?
Brightness is a function of a stars luminosity as observed from Earth. So our Sun is the brightest. Vega has an apparent magnitude of: 0.03 Betelgeuse has an apparent magnitude of 0.42 So, in apparent magnitude, Vega is brighter.
Which star is brighter Betelgeuse or Rigel?
Rigel is brighter than Betelgeuse.
Which is the brighter star aldeberan or Betelgeuse?
Betelgeuse is more luminous than Aldebaran.
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.

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.
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 is brighter Rigel or Betelgeuse?
Rigel is brighter.
Why is Vega brighter than Betelgeuse?
A star's brightness is a function of its luminosity, or the amount of energy it produces per unit time. Vega must have a higher luminosity, meaning it fuses more material than Betelgeuse in a given period of time.
Why is the vega brighter than arcturus?
Arcturus is a bit brighter than Vega, actually.
What is the color and size of the vega star?
Vega is a white star with an A-type spectrum. Its absolute magnitude (magnitude at a standard distance of 10 parsecs) is 0.5 making it 4 magnitudes brighter than the Sun, i.e. 40 times brighter. Its distance is 30 light years.
