Apparent magnitude (Wikipedia) Apparent magnitude (m) is a measure of the brightness of a star or other astronomical object. An object’s apparent magnitude depends on its intrinsic luminosity, its distance, and any extinction of the object’s light caused by interstellar dust along the line of sight to the observer.
