Deneb's absolute magnitude is currently estimated as â8.4, placing it among the most luminous stars known, with an estimated luminosity nearly 200,000 times that of the Sun. This is towards the upper end of various published values over the last few decades.
To figure out luminosity from absolute magnitude, one must calculate that a difference of five on the absolute magnitude scale is equivalent to a factor of 100 on the luminosity scale â for instance, a star with an absolute magnitude of 1 is 100 times as luminous as a star with an absolute magnitude of 6. Limitations of absolute magnitude. While the absolute magnitude scale is astronomers' best effort to compare the brightness of stars, there are a couple of main limitations that have to ...
