    The apparent magnitude of an object is a number that is used to describe the brightness of a star as seen by an observer from the surface of Earth.

    However, apparent magnitude cannot be used to actually measure the brightness of the star because apparent magnitude does not account for distance.

    This means that as the distance between the star and earth increase, the star will look dimmer and as the distance decreases, it will look brighter.
