Labels:text | screenshot OCR: THE SUN'S ENERGY RANDOM WALK THE SUN'S CORE is a nuclear "furnace" Energy generated within the Sun's core takes 2 million years to reach with a temperature of 15 million ℃ the surface, where it is emitted as (27 million "F) and a density 160 times heat and light, and then takes that of water. Under these conditions, only a further 8 minutes to hydrogen nuclei in the core fuse to reach the Earth. form helium nuclei. In the process, The 0.7 percent of the mass being fused Earth is converted into energy. Of the 600 million tonnes (670 million tons) of hydrogen that fuse in the Sun's Random-walk core each second, 4 million tonnes path (4.4 million tons) are converted to energy. The Sun's hydrogen "fuel" will last for another 3 The Sun 5 billion years. SOLAR FACT WIND FILE
