Question

The Earth is bombarded by light from the Sun with a typical, average intensity of about 1370 W/m2 . Based on this, what is the average power of the light that hits Jupiter due to the Sun? The radius of the Earth is 6370 km and the average radius of the Earth’s orbit is 150 Gm. The radius of Jupiter is 69.9 Mm and the average radius of Jupiter’s orbit is 778 Gm

Answer 1

Given average intensity of sunlight on the Earth, average radii of the orbit of the Earth and the Jupiter, radius of the Jupiter, it is asked to find power of sunlight intercepted by the Jupiter. In solving the problem we used the relation Power incident =solar flux density at the orbital distance times shadow area.
