The Sun happens to be powered by fusion, which occurs at the time where four hydrogen atoms collide, eventually fusing together to create one helium atom. The sun experiences such reactions 100 million quadrillion quadrillion times each seconds. During the same time that an existing result, the sun emits the equivalent that belongs to 91 billion megatons of nuclear explosions every second. This significant quantity of energy happens to be predicted by E=mc². Learn more
