Why Vega brighter than Arcturus?
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.

Is Vega or Betelgeuse the brightest star?
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.

A star's brightness is the brightness seen by humans on Earth. A star's brightness is its actual brightness and does not depend on where the star is viewed from.?
The brightness as seen from Earth is called the "apparent magnitude".The real brightness (defined as the apparent brightness, as seen from a standard distance) is called the "absolute magnitude".
What is the measure of the star's brightness?
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
What is a stars brightness as if it were a standard distance?
Theres `Absolute Magnitude` which is the brightness of a star at a set distance. Then there is `Apparent Magnitude` which is the apparent brightness from earth, regardless of distance.
