How Long Does It Take Jupiter to Complete a Rotation?

Jupiter has the shortest day of any planet in the solar system, taking just under 10 hours to complete a single rotation. Due to the speed of its rotation Jupiter has been flattened into an oblate spheroid with a longer diameter at its equator than at the poles.

Jupiter is the fifth and largest planet in the solar system, possessing more than twice the mass of all the other planets combined. While its fast rotation means that a single day on Jupiter lasts just 9.97 hours, it takes Jupiter almost 12 Earth years to complete a single orbit around the Sun.
