The sun is a star near the world most. There are mainly composed of hydrogen at the heart of the sun, temperature and high pressure to come. The hydrogen fusion is the helium gas. And spread the power out immensely as heat and light, we call this reaction. "" thermal energy, nuclear fusion reactions. The light from the sun itself. That encourages the C ฃี life on our planet.The internal structure of the sun consists of1. The core temperatures 15 million K.2. Blazing radiation. Heat transfer to the outside, in the form of wave.3. Convection zone above the radiation zone Thermal energy in this zone are conveyed to the outer part by the movement of gas.4. The surface of the sun photosphere. Above the convection zone. We observe the surface of this part of the light wave is about 5 500 temperature, K.5. The chromosphere. Is the area above the photosphere, up from the floor, high temperature about 10 000 K.6. Corona is the outer atmosphere of the sun spread out in space, many kilometres with high temperature more than 1 million K.
