2.65. It has a white dwarf companion of about 13
Its absolute magnitude is -7.92
Apparent magnitude is 0.77 Absolute magnitude is 2.21Wikipedia lists its visual magnitude as 0.77.
The absolute magnitude is -7.92
Betelgeuse has an apparent magnitude of 0.58 and on absolute magnitude of -6.05.
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.
Procyon is a binary starProcyon A has an apparent magnitude of +0.34Procyon B has an apparent magnitude of +10.7Gomeisa has an apparent magnitude of +2.89So Procyon A is brighter than Gomeisa but Procyon B is dimmer.
Oh, dude, let me drop some knowledge on you. Polaris is about 2,000 times more luminous than Procyon A. It's like comparing a flashlight to the sun... well, not really, but you get the idea. So yeah, Polaris is shining bright like a diamond compared to Procyon A.
Canis Minor has two stars and they are Procyon and Gomeisa. Procyon has the magnitude of 0.4 and Gomeisa has the magnitude of 2.9. It is true that Canis Minor is a constellation and that it doesn't have a magnitude of its own, but its star has its own magnitude.
it is +0.26 wich equalls sex
Antares Absolute and Apparent Magnitude Absolute Magnitude~ -5.2 Apparent Magnitude~ +0.60
Its absolute magnitude is -7.92
In terms of absolute magnitude, some well-known series from brightest to dimmest include: Sirius (absolute magnitude -1.46), Canopus (-5.53), Arcturus (-0.30), and Procyon (+2.65). The sequence continues with stars like Altair (+2.21) and Vega (+0.58), followed by Deneb (+1.25) and Betelgeuse (+1.49). These values indicate their intrinsic brightness, with lower (or more negative) numbers representing brighter stars.
Regulus, also known as Alpha Leonis, is brighter than Procyon, also known as Alpha Canis Minoris. Regulus is a first-magnitude star with an apparent visual magnitude of about 1.35, making it one of the brightest stars in the night sky. Procyon, on the other hand, has an apparent visual magnitude of about 0.34, making it slightly dimmer than Regulus.
The absolute magnitude of Porrima is 3.04.

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.
