The energy radiated by the Sun comes from the conversion of mass into energy during fusion reactions of nydrogen nuclei to produce helium nuclei. Currently, these reactions allow the Sun to emit light radiation at a power of approximately 4 · 104 W. Assuming that this power has been maintained since the birth of the Sun, about 5 · 10º years ago, the mass corresponding to that lost by the Sun until today is closer to Info: Speed of light in vacuum: 3 · 108 m 1 year has approximately 3 · 107 seconds. The equations that relates energy to mass is E = m·c².
