Jupiter has the shortest revolution period and Venus has the longest.


Jupiter has the shortest rotation period at 9 hours 55 minutes. It is closely followed by Saturn which rotates in 10 hours 40 minutes.

The longest rotation period by far is Venus at 243 days. It is also retrograde, meaning that it rotates in the opposite direction to the other planets. It is also longer than its orbital period of 224.7 days.
