Luminosity
... The Luminosity of a star is the energy that it releases per second. Sun has a luminosity of 3.90x1026 W (often written as L): it emits 3.90x1026 joules per second in all directions. The energy that arrives at the Earth is only a very small amount when compared will the total energy released by the ...
