The [[Astronomical Terms Database#Apparent Magnitude|apparent magnitude]] that a [[Star|star]] would possess if it were a distance of 10 [[Astronomical Terms Database#Parsec|parsecs]] from [[Earth|Earth.]] In this way, absolute magnitude provides a direct comparison of the brightness of [[Star|stars.]] A [[Star|star’s]] [[Astronomical Terms Database#Luminosity|luminosity]] and its distance from [[Earth]] provide the basis for its [[Astronomical Terms Database#Apparent Magnitude|apparent magnitude.]] If all [[Star|stars]] were the same distance from [[Earth|Earth,]] then their [[Astronomical Terms Database#Apparent Magnitude|apparent magnitudes]] would only be dependent on their [[Astronomical Terms Database#Luminosity|luminosities.]] Therefore, absolute magnitudes are true indicators of the amount of [[Light|light]] each [[Star|star]] emits. The value is lower, even into the negatives, for objects that appear brighter, and higher for objects that appear dimmer. Absolute magnitude is usually measured through the visible spectrum. However, it can be measured through the entire spectrum. Absolute visual magnitude, through the visible spectrum, is abbreviated as '''''Mv.'''''
