What is the apparrent magnitude of the star Betelguese?
The apparent magnitude of Betegeuse is 0.5 and it has an M2 spectrum making it a red star. Its distance is 420 light years and its absolute magnitude is -4.5 so it is 9 magnitudes brighter than the Sun; that is 4000 times brighter, so it's a giant. It is slightly variable in its brightness. At the same distance the Sun would be a 9th magnitude star, invisible except in a telescope.

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.
