113 How the Sun Works
- Two protons fuse to produce a deuterium nucleus (p + + n 0 ) — a positron, a neutrino, and a lot of energy
- A proton and a deuterium atom combine to form a He-3, Gamma Ray, and energy
- Two He-3 atoms combine to form a He-4 atom, two protons, and energy
It takes about 100,000 years for that energy to get from the sun’s core to the photosphere.
