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.
