Sun heat

It is about million miles (14 million km) from Earth. That distance is called an astronomical unit, or AU, and is used to measure distances throughout the solar system. The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons ( light).
