Kepler's Laws of Orbital Motion. The moon revolves around Jupiter in 48 years and has an orbital radius of 4.2 x 10^6 m. If the Jupiter moon Europa has a period of 0.0097 years, then how far away is Europa from the center of Jupiter? (Answer: 10^10 m) The moon takes 27.32 days to revolve around the Earth once. The moon is 4.1 x 10^8 m from the center of the Earth. The International Space Station makes an orbit around the Earth in 90 minutes. How far away is the International Space Station from the center of the Earth? (Answer: 7.1 x 10^11 m) Jupiter is about 5 times farther away from the Sun than the Earth is. What is Jupiter's orbital period in years? The distance from the Earth to the Sun is 1.04 x 10^11 m. (Answer: 11.18 years)
