Io, Europa, and Ganymede, the three largest moons of Jupiter, have synchronized rotation periods due to a phenomenon known as orbital resonance. Io takes about 1.8 days to complete one rotation, while Europa and Ganymede have rotation periods of about 3.5 days and 7.2 days, respectively. Despite their differing rotation periods, they are locked in a 1:2:4 resonance, meaning that for every one orbit Io makes, Europa completes half an orbit, and Ganymede completes a quarter. This gravitational interaction keeps their rotation periods closely linked.

How do the periods of rotation of io europa and ganymeded compare?

Io, Europa, and Ganymede, the three largest moons of Jupiter, have synchronized rotational periods due to a gravitational phenomenon known as orbital resonance. Io has a rotation period of about 1.8 days, Europa takes about 3.5 days, and Ganymede has a rotation period of approximately 7.2 days. This means that for every orbit of Ganymede, Europa completes about two orbits, and Io completes about four, keeping the moons in a stable, resonant relationship with one another.

How far away is Ganymede from Europa?

Answer is an estimate using mean orbital radius Europa 670,900km Ganymede 1,070,400km So their closest estimated point would 399,500km (not calculating Europa's furthest distance to Jupiter with Ganymede's closest when they're in astronomical alignment)
