WebThe angular diameter of the Earth as seen from the Sun is approximately 1/11,700 radians (about 18 arcseconds ), meaning the solid angle of the Earth as seen from the Sun is approximately 1/175,000,000 of a steradian. Thus the Sun emits about 2.2 billion times the amount of radiation that is caught by Earth, in other words about 3.846×10 26 watts. geotility
