which planet has the shortest day

Jupiter has the shortest day of any planet in our solar system, rotating once in just under 10 hours.

Quick Scoop

  • A day on a planet is the time it takes to complete one full spin on its axis.
  • Jupiter completes that spin in about 9 hours 55–56 minutes, much faster than any other planet.
  • Because of this rapid rotation, Jupiter’s day is the shortest among all eight major planets in the solar system.

So if you are wondering which planet has the shortest day , the answer is Jupiter—and your “day” there would be over before a workday on Earth even hits lunchtime.
