One surprising fact about the sun is that the poles and the equator rotate at different rates. The equator takes 26.8 days to rotate, while the poles take 36 days. This is because the sun is not a solid body but a ball of hydrogen and helium gas.
Despite the fact that at least eight planets orbit it with their dozens of moons and countless asteroids, comets and Kuiper belt objects, the sun still makes up more than 99 percent of the mass of the solar system. About a million Earths fit inside the sun. The sun's equatorial circumference is 2,715,395.6 miles.
It takes light 8 minutes to travel to the Earth from the sun, so if the sun blew up, it would take 8 minutes for the people of Earth to know. The surface, or photosphere, of the sun is about 10,000 degrees Fahrenheit. This is about the same temperature as the inner iron core of the Earth. The temperature increases to about 3.5 million degrees Fahrenheit in the sun's corona, but scientists do not know why this is. The coronal atmosphere extends beyond the orbit of Pluto. The temperature of the sun's core is about 27 million degrees Fahrenheit.
