Brightness is a function of a stars luminousity as seen from Earth.
The Sun is far brighter than Vega.
However, if they were both viewed from the same distance, then Vega would be brighter.
Yes, by several thousand degrees.
Venus surface temp is about 600 degrees F.
The sun's surface temp is about 6000 degrees F. (and the sun's temp goes up as you go inward.)
Yes, the star Vega is hotter than the sun. At 17,000 degrees Fahrenheit, it burns about 7,000 degrees hotter than the sun.
No, The sun is 15 million degrees fahrenheit, while Venus is only 900 degrees at most.
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.
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.
Brightness is related to distance. However, from the same distance, an O class star is much much brighter than a M class star. As a comparison, an O class star would appear about 100,000 times brighter than our Sun, whereas a M class star could appear 0.0017 dimmer than our Sun, if the Sun was replaced with each star.
Vega = 9,602 KelvinThe Sun = 5,778 KelvinBetelgeuse = 3,500 Kelvin
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.
The Sun Shines Brighter was created in 2005.
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.
Tomorrow is going to be a BRIGHTER day. The sun is BRIGHTER today then yesterday. Some day I will shine BRIGHTER than the sun.
