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

Betelgeuse is the brighter star compared to Aldebaran. It is a red supergiant star in the constellation Orion and is one of the brightest stars visible in the night sky. Aldebaran is an orange giant star in the constellation Taurus and is not as bright as Betelgeuse.
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.
Betelgeuse is hotter than Vega. Betelgeuse is a red supergiant star with a surface temperature of around 3,500 degrees Celsius, while Vega is a blue-white star with a surface temperature of around 9,600 degrees Celsius.
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.
Yes, Betelgeuse is one of the brighter stars in the sky. The red star of Orion's left shoulder is 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.
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.
