Interactive Simulator · The Sun as a Star

Light the Core

The Sun is a star: a medium-sized ball of mostly hydrogen and helium. Deep in its core, where it is incredibly hot, hydrogen nuclei fuse into helium and release huge amounts of energy. That energy is what lights and warms the whole Solar System. Heat the core to the right temperature for steady fusion.

Mission Set the core temperature for steady fusion: target 18 units. Round 1Streak 0Best 0
