Best Answer

Nuclear fusion occurs in stars due to the shear density of a star. They are so dense that the pressure in the core ionizes hydrogen, stripping them into bare atoms. The inward gravitational pull of the dense core causes the atoms to be smashed together, fusing into helium. The energy from the fusion provides enough outward pressure to counteract the core's own gravity.
