Fusion The fusion of hydrogen into helium is how the Sun produces energy to keep its temperature and pressure high enough to resist gravity. • The Sun is powered by NUCLEAR ENERGY, so the Sun shines. Gravitational Equilibrium The outward push of pressure balances the inward pull of gravity. • Weight of upper layers of Sun compresses lower layers; high density and high
