Why does Saturn radiate even more excess heat than Jupiter?

Question

Quizplus · Accepted Answer

Saturn radiates more excess heat than Jupiter primarily because of the phenomenon known as "helium rain." This process involves helium droplets forming in the upper layers of Saturn's atmosphere and then falling deeper into the planet. As these droplets descend, they release gravitational potential energy as heat. This contributes significantly to the excess heat observed from Saturn, making it radiate more than would be expected from solar heating alone.
