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.
Venus has the longest day 243 earth days long. In fact its day is longer than its year (224.7 Earth days)!. Scientists think it is because of Venus's dense atmosphere that causes the slower rotation. Then their is its orbit around the sun which is nearly circular and it is the only planet with such an orbit. curious aspect of Venus's orbit and rotation periods is that the 584-day average interval between successive close approaches to the Earth is almost exactly equal to five Venusian solar days.
