How are absolute magnitude and luminosity related?

Two of the main types of magnitudes distinguished by astronomers are: • Apparent magnitude, the brightness of an object as it appears in the night sky. • Absolute magnitude, which measures the luminosity of an object (or reflected light for non-luminous objects like asteroids); it is the object's apparent magnitude as seen from a specific distance, conventionally 10 parsecs (32.6 light years).
