Ganymede doesn't orbit the Sun directly. It orbits Jupiter, which in turn orbits the Sun.

Here's the breakdown:

* Ganymede's orbital period around Jupiter: Approximately 7.15 Earth days.

* Jupiter's orbital period around the Sun: Approximately 11.86 Earth years.

So, while Ganymede takes a little over a week to go around Jupiter, it takes Jupiter almost 12 years to complete one orbit around the Sun.
