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.
This means that Venusâ day is longer than itâs year! It is orbiting the sun faster than the time it takes to completely rotate on its axis. On Uranus, a day takes nearly 18 Earth hours. This means that while Uranusâ day is shorter than Earthâs, its year is significantly longer! This means that Uranus is rotating very fast when compared to Earth, and orbiting the sun very slow (because it is so far away).
