This statement accurately describes the concept of absolute magnitude. It is a measure of a star's inherent brightness, or how bright it would appear if it were viewed from a standard distance of 10 parsecs (or 33 light years) away. This allows for a more meaningful comparison of different stars since their apparent brightnesses can be affected by their distances from Earth.
