In the brightest constellation Orion are bright stars, as blue-white Rigel and Betelgeuse a golden orange (pictured below), but none surpasses Sirius .
Rigel is a blue star, which is part of the constellation Orion, located in the bottom right of the Hunter.
Slightly lower in brightness than Capella, Rigel is a classic example of a blue giant, very hot, blue, and bright. Rigel was once considered to be brighter than any of the other giants that populate the Orion region. Now we think that is a little closer to us, about 800 light-years away, than previously estimated.
So maybe Rigel is just one of the brightest stars in the winter sky. Even so, its brightness is thousands of times greater than that of our sun.
