Why is Betelgeuse so luminous?
Betelgeuse is luminous because it is a red supergiant star in the late stages of its evolution. Its large size and high brightness are due to its immense amount of energy being produced as it fuses heavy elements in its core, leading to its intense brightness compared to smaller, main-sequence stars.
How much brighter is betelgeuse than the sun?
Betelgeuse, a red supergiant star, is approximately 10,000 times brighter than the Sun. Its immense brightness is due to its large size and high luminosity, which allows it to outshine our Sun considerably. While the Sun is the brightest object in our sky, Betelgeuse's inherent brightness makes it one of the most luminous stars observable from Earth.
