The sun contains hydrogen and helium. The sun didn't burn by changing the hydrogen gas is helium gas. The sun is very hot ในรบ around sun at the center, the sun will heat the 15 million degrees Celsius This heat is only as big as pinhead, it will make the people standing away 150 kilometers die.The sun is a star in the center of the solar system. เนื้อสาร most of the solar system is where the sun is up to 99.87% is mass planets together at least more than 0.13% sun star small Compared with the other stars in the sky, but the stars near earth. Therefore appears in a circle, in the sky of the world only one heart. Another star appears as a bright spot because it is very far. The actual size is bigger than the earth. A diameter almost 109 times of the world.The sun produces energy itself by changing the เนื้อสาร energy according to Einstein's equation E = MC2 (E is energy, M is เนื้อสาร,, C is the speed of light in space and light, which is about 300 000 kilometers per second). The เนื้อสาร become energy is the core which has high temperature to 15 million degrees Celsius at the core of the sun has a hydrogen bomb). A thermonuclear reaction was about to explode. The combination of a helium hydrogen Each second of 4 million tons of hydrogen energy in 1 years become the sun compared to all the มวลสารของ 2 x 1027 tons. Or 2 000 trillion tons, or 332 946 times, of the world.
