Question

Quizplus · Accepted Answer

Apparent magnitude tells us the brightness of a star as it appears in our sky. It is a measure of the amount of light that reaches our eyes or telescopes from the star. It is not a measure of the star's intrinsic brightness or its size. The apparent magnitude of a star depends on its distance from Earth, as well as its intrinsic brightness.
