Which planet in our solar system has the shortest day?

Jupiter is the planet in our solar system with the shortest day. It takes just under 10 hours for Jupiter to complete one rotation on its axis, making it the fastest rotating planet in our solar system. This rapid rotation causes Jupiter to have a distinct shape, with a bulging equator and flattened poles.

Other planets in our solar system have much longer days. For example, a day on Venus, the slowest rotating planet, is longer than its year, with a day lasting 243 Earth days. Mars has a day length similar to Earth, with a day lasting around 24.6 hours.

Scientists have been able to measure the length of a planet's day by observing patterns in its atmosphere or by tracking the rotation of its magnetic field. With advanced technology, we can learn more about the unique characteristics of each planet in our solar system.

Jupiter has the shortest day in our solar system. It takes only about 9 hours and 55 minutes for Jupiter to rotate once on its axis. This is because Jupiter is a gas giant, and gas giants are very good at spinning. The faster a planet spins, the shorter its day will be.
