Jupiter rotates on its axis most rapidly out of all of the planets, 9h 55m 30s for one full spin, compared to Earth which takes around 24 hours.
Earth, but there's not much difference.

The length of a planet's day is directly related to its rate of rotation on its axis. A faster rate of rotation results in a shorter day, while a slower rate of rotation leads to a longer day. This relationship is determined by the planet's mass and distribution of mass.

What is planet Jupiter's rotation on axis time
Jupiter in the planet with the shortest rotation time, with a day approximately 12 hours long.
We use the word "day" to indicate the time between sunrises. On Earth, the "day" is 24 hours. Planets that rotate more rapidly have shorter days, while planets that rotate slowly have longer days.
The rotation of a planet refers to the planet spinning like a top; a "revolution" is the time required for the planet's orbit around the Sun.
Mercury
A planet's period of rotation refers to the time it takes for the planet to complete one full rotation on its axis. This is what determines the length of a day on that planet. For example, Earth's period of rotation is approximately 24 hours, which is why we have a 24-hour day.
Jupiter is less dense and has a shorter period of rotation.
