One example of a star that is more massive than our Sun but has a lower surface temperature is Betelgeuse. This red supergiant star, located in the constellation Orion, has a mass roughly 10-20 times that of the Sun, yet its surface temperature is around 3,200 K, compared to the Sun's surface temperature of about 5,800 K. Betelgeuse is much larger in diameter and luminosity, but its cooler temperature is characteristic of its late-stage evolution.
