Bright giants - the stars lying between giants and supergiants . On the one hand, these stars have a luminosity comparable to the luminosity of supergiants, but on the other hand they are usually not massive enough to be classified as supergiants. The mass of bright giants may not exceed several masses of the Sun.

The bright giants are on the Hertzsprung-Russell diagram under supergiants and include spectral class stars from “B” to “M”. In their left (hot) part, their track descends steeply - from “B” to “A”, then runs almost horizontally. The luminosity of bright giants surpasses the Sun on average 650 times.

In the Yerkeskoye classification, taking into account the luminosity, the bright giants are assigned the luminosity class II, which suggests an average absolute magnitude of −2.2 ^m .
