* Length of a day: Jupiter spins very quickly! A single rotation (a day) on Jupiter takes approximately 9 hours and 55 minutes.

* Length of a year: Jupiter takes a much longer time to orbit the Sun. It takes about 11.86 Earth years for Jupiter to complete one orbit.

Key Point: These times are based on how long it takes Jupiter to rotate on its axis (day) and complete one orbit around the sun (year) from our perspective here on Earth.
