It all depends on where you view them from.
The apparent magnitude, is defined as being viewed from Earth
Betelgeuse: 0.58 - Brighter
Zeta Orionis (Alnitak) = 1.70
The absolute magnitude, is defined as being viewed from a distance of 10 parsecs.

Which star is brighter Betelgeuse or Rigel?
Rigel is brighter than Betelgeuse.
Why is Jupiter in the night sky brighter than betelgeuse?
Jupiter is brighter than Betelgeuse in the night sky because it is much closer to the Earth in comparison to Betelgeuse(Betelgeuse is more than 500 lightyears away form the Earth). This way, Jupiter appears larger than Betelgeuse, and celestial objects that appear larger also appear brighter than objects that appear small.
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 is the brighter star aldeberan or Betelgeuse?
Betelgeuse is more luminous than Aldebaran.
Is Betelgeuse warmer than the sun?
No. While Betelgeuse is larger and brighter than the sun, it actually has a lower surface temperature.
When Betelgeuse explodes will it swallow us up?
No, it is much too far away for that. We will see it get much brighter in the sky, much brighter than any other star. But, other than the pretty light show, it won't affect us.
What is Betelgeuse going to do when it dies?
Betelgeuse will die in a massive explosion called a supernova. When this happens it will appear brighter than the full moon.
Does our sun have a lower absolute magnitude then Betelgeuse?
Our sun has an absolute magnitude of 4.83, compared to Betelgeuse's absolute magnitude of -6.05. This means that Betelgeuse is more than 10 magnitudes brighter than our sun.
How much brighter than Sirius would the Betelgeuse supernova be in your sky if it reached a maximum luminosity?
The supernova would be so much brighter that it's hard to compare, at least 10 magnitudes brighter then Sirius. It would probably be about the same brightness as the full moon in the sky.
Is the sun smaller than Betelgeuse?
Yes, the Sun is much smaller than Betelgeuse.
How can you tell that Rigel is brighter than Betelgeuse?
The simple answer is by looking at them.The technical answer is by analysing their bolometric luminosity with a bolometer.
Which is larger Rigel or Betelgeuse?
Betelgeuse is much larger than Rigel.
