Answer:
The correct answer is "Absolute Magnitude".
Explanation:
Absolute magnitude is a measure of luminosity applied to celestial objects such as stars. In contrast to other measures such as apparent magnitude, absolute magnitude uses a standard distance from Earth as scale, particularly, the distance of exactly 10 parsecs (32.6 light-years). The symbol of absolute magnitude is "M", and in the case of stars, it usually has a measure from −10 to +17.
