sentences:  It is estimated to have about 50% more mass than the Sun, while interferometric measurements show it to be 15 times larger in diameter.Despite its enlarged girth, this star is still spinning with a slightly faster equatorial azimuthal velocity than the Sun, having a projected rotational velocity of 3.44 km s−1.Hamal is radiating about 91 times the Sun's luminosity from its outer envelope at an effective temperature of 4,480 K. This is cooler than the surface of the Sun, giving it the orange-hued glow of a K-type star.
