Q:

How long does it take Jupiter to rotate on its axis?

A:

Jupiter completely rotates on its axis once every 9.9 hours. Jupiter rotates faster than any other planet in the solar system. Determining the rotation speed of Jupiter is complex due to the fact that it is a gaseous planet without many consistent landmarks to track.

Due to the composition of the planet, Jupiter rotates approximately 5 minutes slower at its poles than at its equator. The speed of 9.9 hours is the average for all points on the planet. Jupiter completes an orbit around the sun once every 11.8 Earth years, or 4,332 Earth days. Jupiter is comprised almost entirely of hydrogen and helium.
