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.
No, Betelgeuse is not a quasar. Betelgeuse is a red supergiant star located in the constellation of Orion, while a quasar is a highly energetic and distant active galactic nucleus powered by a supermassive black hole at the center of a galaxy.
