    Io takes about 42.5 hours to complete one orbit around Jupiter and is in a 2:1 mean-motion orbital resonance with Europa and a 4:1 resonance with Ganymede. This means that it completes two orbits of Jupiter for every one orbit of Europa, and four orbits for every orbit Ganymede.

    How old is Io compared to Jupiter?
    Age: Io is about 4.5 billion years old, about the same age as Jupiter. Distance from Jupiter: Io is the fifth moon from Jupiter. Its average orbital distance is about 262,000 miles (422,000 km). Io takes 1.77 Earth -days to orbit Jupiter. Io is tidally locked, so the same side always faces Jupiter.

    What is Io orbital period?
    Io orbital period, i.e. the period it takes to complete an orbit round Jupiter is 1.76914 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A.. The orbital inclination of Io, the angle at which Io orbits to the orbital plane, is 0.04 degrees.

    How many times does Io orbit Jupiter?
    The ratios of the orbital periods of the inner three Galilean moons are simple integers: Io orbits Jupiter twice every time Europa orbits once, and four times for each revolution by Ganymede; this is sometimes referred to as the Laplace resonance.

    How many orbits does Io make If Ganymede goes around Jupiter?
    Io is in a tug-of-war with Ganymede and Europa, and Europa’s orbital period (time to go around Jupiter once) is twice Io’s period, and Ganymede’s period is twice that of Europa. In other words, every time Ganymede goes around Jupiter once, Europa makes two orbits and Io makes four orbits. The moons all keep

    What is the orbital inclination and eccentricity of Io?
    The figure comes from N.A.S.A.. The orbital inclination of Io, the angle at which Io orbits to the orbital plane, is 0.04 degrees. The orbital eccentricity is 0.0041 of Io, the degree at which Io orbits close to a circular (0) orbit as opposed to an elliptical (1).

    Why is Io tidal?
    Although Io always points the same side toward Jupiter in its orbit around the giant planet, the large moons Europa and Ganymede perturb Io's orbit into an irregularly elliptical one. Thus, in its widely varying distances from Jupiter, Io is subjected to tremendous tidal forces.

    Io's orbit, keeping it at more or less a cozy 262,000 miles (422,000 kilometers) from Jupiter, cuts across the planet's powerful magnetic lines of force, thus turning Io into a electric generator. Io can develop 400,000 volts across itself …
