Science: "THE SUN" The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma,[18] 20]heated to incandescence by nuclear fushion reactions in its core, radiating the energy mainly as light and infrared radiation. It is by far the most important source of energy for life on Earth. Its diameter is about 1.39 million kilometres (864,000 miles), or 109 times that of Earth, and its mass is about 330,000 times that of Earth.
