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.
In the northern hemisphere, the longest day of the year is 21st June and the shortest day is 22nd December. The exact date can vary by a day or so. The same dates apply in the southern hemisphere, but with longest and shortest reversed. The summer solstice is the longest day of the year; the winter solstice is the shortest. In the northern hemisphere, the summer solstice is generally June 21, and the winter solstice is December 21. (Reverse these for the southern hemisphere.)
