Glossary term: Absolute Magnitude

Description: Absolute magnitude is a measure of how bright an object would be when viewed from a standard distance of 10 parsecs. This standardized number allows different objects to be compared in brightness. This is in contrast to apparent magnitude which is a measure of object brightness from the location of the observer.
