Absolute magnitude (M) is a measure of the luminosity of a celestial object on an inverse logarithmic astronomical magnitude scale. An object's absolute magnitude is defined to be equal to the apparent magnitude that the object would have if it were viewed from a distance of exactly 10 parsecs (32.6 light … Meer weergeven In stellar and galactic astronomy, the standard distance is 10 parsecs (about 32.616 light-years, 308.57 petameters or 308.57 trillion kilometres). A star at 10 parsecs has a parallax of 0.1″ (100 milliarcseconds). … Meer weergeven For a meteor, the standard distance for measurement of magnitudes is at an altitude of 100 km (62 mi) at the observer's zenith Meer weergeven • Araucaria Project • Hertzsprung–Russell diagram – relates absolute magnitude or luminosity versus spectral color or surface temperature. Meer weergeven For planets and asteroids, a definition of absolute magnitude that is more meaningful for non-stellar objects is used.

Therefore, it is of greater use in stellar astrophysics since it refers to a property of a star regardless of how close it is to Earth.
http://www.differencebetween.net/science/difference-between-absolute-and-apparent-magnitude/ 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).
