I assume you mean the absolute magnitude (brightness) of stars. The problem with this is that it can't be directly measured. What astronomers can measure is the apparent magnitude. To make conclusions about the absolute magnitude, they would also have to know the distance to the star, as well as data about extinction, i.e., how much dust and gas there is between us and the start which may make the light look fainter. Note that the absolute magnitude is very important to characterize a star - but it may be difficult to calculate it with much precision.
An estimation of the absolute magnitude is −20.9. See related question.
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
Apparent magnitude is 0.77 Absolute magnitude is 2.21Wikipedia lists its visual magnitude as 0.77.
Constellations don't have an absolute magnitude. That is a property of individual stars.
That's the number called the star's "Absolute Magnitude".That is called the star's "absolute magnitude".
the absolute magnitude is 0.48 <(-.-<)
