Final answer:
One day on Jupiter is equivalent to 9 hours 56 minutes, making it the shortest day of any planet in our solar system.
Step-by-step explanation:
Jupiter, the largest planet in our solar system, rotates very quickly on its axis. Through the measurement of periodic variations in radio waves, which are influenced by Jupiter's magnetic field that originates deep inside the planet, scientists have determined that one day on Jupiter is equal to 9 hours 56 minutes. This rapid rotation means that Jupiter has the shortest day of any planet in our solar system. Comparatively, Saturn has a rotation period of 10 hours 40 minutes, and Uranus and Neptune have rotation periods of about 17 hours, based on their magnetic field rotations.
