Io is a moon of Jupiter. Io has a mass of 8.9319×1022 kg and Jupiter has a mass of 1.898×1027 kg. Jupiter's orbital period around the Sun is 11.86 years and it is primarily composed of molecular and metallic (!) hydrogen. They are separated by a distance of 448000 km. If a small satellite is on the line between the two objects and feels no net gravitational force from the two bodies, what is the distance between Io and the satellite?
