A supergiant star has an atmosphere that extends far from the star's center. On a surface area basis, square meters say, the surface is very dim. But since the size is so great the overall brightness is high. Betelgeuse is a good example. The outer atmosphere is so tenuous that there is actually a star orbiting within it. But it is so large that it shines brightly at the right shoulder of Orion.
