Apparent magnitude is the brightness of a star as it appears
... Apparent magnitude is the brightness of a star as it appears from Earth. This brightness depends partly on how far away the star is. Absolute magnitude describes the actual brightness of a star without considering its distance from the observer. The absolute magnitude of stars is measured on a Scale ...
