WebNov 13, 2012 · Nuclear fusion at the core of the sun turns hydrogen into helium and provides enough power to keep our star shining for ten billion years. Learn more here. WebOnly the inner 10% of the Sun is hot enough for fusion to occur. Whenn all these factors are taken into account, we find: Fusion Lifetime is ~10 Billion Years. Modern estimates from radioactive dating give an age of the Earth of 4.6 Billion years. The Sun can potentially shine for about twice that, averting the age crisis. graped definition
