Vega is the brighter of the two stars. It is one of the brightest stars in the night sky and is located in the constellation Lyra. Betelgeuse is also a bright star, but it is not as bright as Vega and is located in the constellation Orion.
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.
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.
It is better to say that the sun appears brighter because it is closer. Some stars are actually brighter than the sun.
The galaxy IRAS is approximately 25 times brighter than the Sun.
Arcturus is a bit brighter than Vega, actually.

1. It might be closer to us, 2. it might be a bigger and brighter star. Arcturus is 35 light years away and has an absolute magnitude of -0.3, which makes it 100 times brighter than the Sun, while Vega is 26 light years away and has an absolute magnitude of 0.5, about half as bright as Arcturus. From Earth they are both about the same brightness.
Vega appears brighter than Arcturus in the night sky because it is closer to Earth, being only about 25 light-years away compared to Arcturus which is around 37 light-years away. Additionally, Vega is a hotter and more luminous star compared to Arcturus, contributing to its perceived brightness.
The apparent brightness of stars depends on:* The distance * The actual brightness * In some cases, the brightness may be dimmed by clouds of dust and gas, between us and the distant star. In the case of Vega and Arcturus, Vega is NOT brighter than Arcturus. Their apparent magnitude (brightness) is about the same, with Arcturus perhaps being slightly brighter, depending on the source consulted. In terms of real brightness ("absolute magnitude"), Arcturus is actually brighter. When consulting numbers, please remember that smaller numbers refer to brighter objects.
The distance from the sun to the star Vega is roughly 25.3 light years.
The Sun Shines Brighter was created in 2005.
Tomorrow is going to be a BRIGHTER day. The sun is BRIGHTER today then yesterday. Some day I will shine BRIGHTER than the sun.
Brighter Than the Sun was created on 2011-05-23.
