WebSep 17, 2024 · Even though Rigel is often referred to as the most luminous star within 1,000 light years of Earth, the star’s luminosity is still uncertain. Based on the currently accepted distance of 860 light years, its estimated luminosity is about 120,000 times that of the Sun. However, a recent study gives a distance of 1,170 ± 130 light years, which ... WebThe absolute magnitude of a star is another measure of its luminosity. The magnitude system that we use now is based on a system used by the ancient Greeks over 2,000 years ago that classified stars by how bright they appeared. A star's absolute magnitude is the apparent magnitude it would have if it were at a distance of 10 parsecs from Earth.
Webluminosity, in astronomy, the amount of light emitted by an object in a unit of time.
