The orbit of Io, a moon of Jupiter, is found to have a period of 1.769 days, and its average distance from the center of Jupiter is 420,000 km. The mass of Jupiter

Question

Quizplus · Accepted Answer

The mass of Jupiter can be determined using Kepler's third law of planetary motion, which relates the orbital period of a satellite to the mass of the central body (in this case, Jupiter) and the average distance of the satellite from the central body. The given information about Io's orbital period and average distance from Jupiter is sufficient to calculate Jupiter's mass, without needing to know the mass of Io. The correct calculation leads to the mass of Jupiter being approximately 1.9 $\times$ 10^27 kg.
