Considering there are over 10 sextillion stars in the visible Universe, listing them - at one a second - would take over 31,688,764,600,000 (31 trillion) years and I'm sorry I just don't have that much time.

The brightness of a star depends on its temperature, size and distance from the earth. The measure of a star's brightness is called its magnitude. Bright stars are first magnitude stars. Second magnitude stars are dimmer. The larger the magnitude number, the dimmer is the star.The magnitude of stars may be apparent or absolute.
Astronomers define star brightness in terms of apparent magnitude (how bright the star appears from Earth) and absolute magnitude (how bright the star appears at a standard distance of 32.6 light years, or 10 parsecs).
This has nothing to do with shape. The apparent magnitude means how bright a star looks to us. The absolute magnitude means how bright the star really is (expressed as: how bright would it look at a standard distance).
The two ways are by their surface temperature (spectrum) and by their absolute magnitude (intrinsic brightness). The HR diagram has spectrum along the horizontal axis and absolute magnitude along the vertical axis. Each star occupies a point in the HR diagram.
Constellations don't have an absolute magnitude. That is a property of individual stars.
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.
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
Absolute magnitude
Apparent magnitude and 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.
The term is "absolute magnitude".
It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.
The apparent magnitude is how bright the star appears to us, but stars are all at different distances so that a star that is really bright might look dim because it is very far away. So the absolute magnitude measures how bright the star would look if it was placed at a standard distance of 10 parsecs. When the absolute magnitude is greater than the apparent magnitude, it just means that it is closer than 10 pc. The brightest stars have absolute magnitudes around -7.
