Something is missing from your question. Cygni is not a star. The constellation name is Cygnus. The star will have a name like Alpha Cygni or 25 Cygni.
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.
Cygni refers to the constellation Cygnus (the swan). Cygnus comprises tens of stars - not just one. These are of different magnitude and so the question is meaningless.
The simple answer is that it does not. It is important to note that stars radiate across a whole range of electromagnetic frequencies, not just in the visible part of the spectrum. Astronomers use bolometric absolute magnitude to adjust for the fact that a star may be radiating much of their energy outside of the visible range. Using the bolometric absolute magnitude, the brightest star, with magnitude -12.5 is RMC136a1 in the Large Magellanic Cloud, at a distance of 163000 light years.Among stars visible to the naked eye, Bellatrix does not even make it to the top ten in terms of its bolometric absolute magnitude. That distinction goes to P Cygni with an absolute magnitude of -9.7. It is 5900 light years away. In comparison, Bellatrix has a magnitude of only -2.64
Antares Absolute and Apparent Magnitude Absolute Magnitude~ -5.2 Apparent Magnitude~ +0.60
Its absolute magnitude is -7.92
The absolute magnitude of Porrima is 3.04.
The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.
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 <(-.-<)
