The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.

Constellations don't have an absolute magnitude. That is a property of individual stars.
Apparent magnitude is the brightness as observed from earth, while absolute magnitude is the brightness of a star at a set distance. The apparent magnitude considers the stars actual brightness as well as it's distance from us, but absolute magnitude takes the distance factor out so that star brightnesses can be directly compared.
The question is: Why is the apparent magnitude of some stars less than their absolute magnitude. Or: Why do some stars not look as bright as they really are ? The answer is: Because they're so far away from us.
Absolute magnitude
Most "yellow" stars fall into the classification of type G - the same as our Sun.They have an absolute magnitude of around 5.
Its absolute magnitude is -1.20.Its magnitude from our point of view is +3.65.
Absolute magnitude: they are extremely bright. Temperature: their surface temperature is fairly low.
Cassiopeia is a constellation, not a single star, so it does not have a specific absolute magnitude. The stars within the constellation Cassiopeia have a range of absolute magnitudes depending on their distance and luminosity.
It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.
The approximate absolute magnitude of Rigel is about -7.0. This makes it one of the brightest stars in the night sky.
