What is the intensity of sunlight per square meter reaching Saturn compared to the intensity at Earth's orbital distance?

Question

Quizplus · Accepted Answer

The intensity of sunlight decreases as distance from the Sun increases. Saturn is approximately 9.5 times farther from the Sun than Earth is, so the intensity of sunlight per square meter at Saturn is 1/9.5 (or approximately 0.105) times the intensity at Earth's orbital distance. Therefore, the answer is A) 1/91, which is the reciprocal of 0.105.
