Why does a cool distant super giant star such as Betelgeuse have such a high apparent magnitude?
Despite its distance and size, Betelgeuse has a high apparent magnitude because of its immense luminosity. It is a massive and highly luminous red supergiant star, shining brightly due to its large surface area and energy output. This makes it appear bright in our sky despite being relatively far away.
