The best measure of a star's brightness is apparent magnitude. Apparent magnitude describes how bright a star appears from Earth, taking into account both its intrinsic brightness and its distance from us. On the other hand, absolute magnitude measures a star's intrinsic brightness at a standard distance (10 parsecs) and size and age do not provide direct measures of bright strength.
