Energy Source of the Sun 1. The suns energy source is nyclear energy Fission - the breaking up of large nucleaus into smaller pieces. Nuclear power plants Fusion - the combinging of two smaller nuclei to form a heavier one. Like how charges repel eachother High temperature and density that occur in the sun 2. The proton - proton cycle is the main thermonuclear fusion reaction in the sun The net effect of these reactions is to convert 4 hydrogen atoms into 1 helium atom Mas of 4 hydrogen atoms = 6.693 X 10^-27 kg Mass of 1 helium atom = -6.645 X 10^-27 kg Unaccounted mass = 0.048 X 10^-27 kg E = mc^2 = 4.3 X 10^-12 joules 3. The suns energy production is equal to 100 million megaton H bombs per second 4. It takes about 1 million years for a photon created in the core of a star to work its way to the surface, even by traveling at the speed of light. 5. The only thing we can detect from the interior of the sun are the neutrinos produced in the PP cycle 6. Neutrinos have no electrical charge and very little mass
