The Sun was born about 4.6 billion years ago, and has been shining over and nurturing us and all lives on the earth. The major difference in the structure between the Sun and the Earth or the moon is that it is entirely composed of high temperature gases. The Sun is structured with roughly three layers of the core, radiate layer and convection layer, and among these three layers, the core, in particular, has the highest temperature and density, and generates the sources of light and heat by nuclear fusion. This generated energy fills the radiate layer and it is carried to the surface (photosphere) by actions in the convection layer. Actually, however, it takes hundreds of thousand years before the energy generated in the core reaches the surface of the Sun, and the energy travels the distance between the Sun and the Earth around 150 million km to reach us.
