Core area of the gas is highly compressed to the density of water 150 times. In a fusion happened here, every second there are 700 million tons of hydrogen are converted into helium. In the process, about 5 million tons of net energy release (equivalent to about 38,600 Yiyi MJ, 3.86 behind 26 0). Fusion energy through the process of convection and radiation field transmission. The energy produced from the core through several million years to reach the surface.

太阳的能量来源于其核心部分。太阳的核心温度高达1500万摄氏度,压力相当于2500亿个大气压。核心区的气体被极度压缩至水密度的150倍。在这里发生着核聚变,每秒钟有七亿吨的氢被转化成氦。在这过程中,约有五百万吨的净能量被释放(大概相当于38600亿亿兆焦耳,3.86后面26个0)。聚变产生的能量通过对流和辐射过程向外传送。核心产生的能量需要通过几百万年才能到达表面。
