Outer Solar System. The planet Jupiter has the shortest day of all the eight major planets in the Solar System. It spins around on its axis once every 9 hr 55 min 29.69 sec. Jupiter has a small axial tilt of only 3.13 degrees, meaning it has little seasonal variation during its 11.86-year-long orbit of the Sun.
Compared to Earth, Mercury has a very long day. A day on Mercury takes 58 days and 15 hours in Earth days. A day on Mercury is only a little shorter than a year on the planet. Venus is the slowest moving planet. In fact, it is so slow that while the other planets have flattened out at the poles due to the speed at which they spin, Venus has not flattened.
