- Satellite 1 has a mass m_1m1 and is located a distance r_1r1 away from the center of its host planet. Satellite 2 has half the mass as Satellite 1, but is located four-times the distance from the center of the host planet as Satellite 1. Determine the ratio of the magnitudes of the force of gravity between Satellite 1 and the planet to the force of gravity between Satellite 2 and the planet Ratio = Fplanet-on-1/ Fplanet-on-2Jupiter has lots of moons in orbit around it. One of those moons, Io, was first observed by Galileo (using an early telescope). Io has an average orbital radius about Jupiter of about 4.2 x 108 m and an orbital period of about 1.8 days. Using this data, calculate Jupiter’s mass.Let planet A have a mass of 5.44 x 1045 kg and planet B have a mass of 2.77 x 1033 If they are attracted by a gravitational force of 6.59 x 103 N, how far apart are their centers of mass
