Rigel is brighter than Betelgeuse.
Procyon is a binary starProcyon A has an apparent magnitude of +0.34Procyon B has an apparent magnitude of +10.7Gomeisa has an apparent magnitude of +2.89So Procyon A is brighter than Gomeisa but Procyon B is dimmer.
Betelgeuse is brighter.
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.
Betelgeuse is more luminous than Aldebaran.
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.
No. While Betelgeuse is larger and brighter than the sun, it actually has a lower surface temperature.
Rigel is brighter.
Betelgeuse will die in a massive explosion called a supernova. When this happens it will appear brighter than the full moon.
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.
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. Betelgeuse: -5.14 Zeta Orionis: -5.25 - Brighter
