One nominal solar luminosity is defined by the International Astronomical Union to be 3.828×1026 W. The Sun is a weakly variable star, and its actual luminosity therefore fluctuates. The major fluctuation is the eleven-year solar cycle (sunspot cycle) that causes a quasi-periodic variation of about ±0.1%.
