Labels:text | screenshot | font | number OCR: FACT FILE ..................... . . . . . . . . . . . . . . . . . . . BETELGEUSE, a pulsating red-supergiant star, has a very low density. It has an average diameter about 400 times that of the Sun, which produces an average volume 64 million times greater than the Sun's volume. Since Betelgeuse contains only about 13 times the mass of the Sun, its average density is 3,500 times less than the density of air. The average density of the Sun is 1,400 times greater than the density of air.
