Recall that the solar constant-the flux of solar energy reaching Earth's vicinity- is about 1390 W/m^2. ( ) (The distance from the sun = 1 AU = 1.50×10¹¹ m.) The Sun's energy originates from a chain of fusion reactions; each reaction chain releases 26.7 MeV of mass energy. At what rate does the Sun lose mass? Express the result in kilograms per year.
