The Sun is not the brightest star known to man. It is a rather ordinary star.
There are two ways to describe brightness in stars : absolute magnitude and apparent magnitude. The lower the number, the brighter the star. Apparent magnitude is how bright the star appears to us from Earth. Absolute magnitude is the brightness if each star was placed at a distance of 10 parsecs. The brightest apparent mag star (other than the Sun) is Sirius with a magnitude of -1.5, then Canopus (-0.7).
Absolute magnitude of stars visible to the naked eye are
Rigel (-6.7) and Deneb (-7.2). The Sun's absolute magnitude is about 4.8.
Hope this helps

If you mean the star that looks the brightest form here, it's Sirius. The absolute brightest star would probably be a class 1A supernova.

It is the perfect answer.

Sirius from Rigel.
Our sun is indeed a star, but it is only brighter in apparent magnitude (brightness on Earth.) and not in absolute magnitude (Brightness at one astronomical unit, distance of Earth from sun).
