Like most known moons, \n Ganymede is tidally locked, with one side always facing toward the planet, hence its day is \n seven days and three hours. Its orbit is very slightly eccentric and inclined to the Jovian \n equator, with the eccentricity and inclination changing quasi-periodically due to solar and \n planetary gravitational perturbations on a timescale of centuries. \n The ranges of change are 0.0009–0.0022 and 0.05–0.32°, respectively. \n These orbital variations cause the axial tilt to vary between 0 and 0.33°. \n\nGanymede participates in orbital resonances with Europa and Io: for every orbit of Ganymede, \nEuropa orbits twice and Io orbits four times. The superior conjunction between Io and Europa \nalways occurs when Io is at periapsis and Europa at apoapsis. \nThe superior conjunction between Europa and Ganymede occurs when Europa is at periapsis. \nThe longitudes of the Io–Europa and Europa–Ganymede conjunctions change with the same rate, \nmaking triple conjunctions impossible. Such a complicated resonance is called the Laplace \nresonance.
