Question

Quizplus · Accepted Answer

The apparent magnitude of a star is affected by both its intrinsic brightness (absolute magnitude) and its distance from Earth. In this case, both stars have the same absolute magnitude, so they have the same intrinsic brightness. However, since star B is closer to Earth than star A, it will appear brighter (have a lower apparent magnitude). Therefore, option B is correct.

Star a and Star B Both Have an Absolute Magnitude
