This is a video about the sun and its heat. The sun's temperature is about 10,000 degrees Fahrenheit at the surface and about 27,000,000 degrees Fahrenheit at the core. The sun is a star. It doesn't have a surface, it's just a giant ball of gas. It's own gravity holds it together. The sun does not have any rings, unlike some planets in our solar system (*cough cough* NEPTUNE *cough). The sun provides all of earth's energy; yes, we get energy from food, too, but without the sun, there'd be no food, so there you go. The diameter of the sun is 1,391,684 kilometers. That's HUGE!
