Best Answer

Jupiter rotates the fastest, taking less than 10 hours to complete one rotation on it's axis. Saturn comes in second, taking just over 10 hours to complete one rotation. Uranus takes about 18 hours and Neptune takes about 19 hours.

Earth, Mars, Mercury, and Venus all take at least a full Earth day to rotate once.

The basic answer is "the equator".

Here's more detail:

If the planet is solid, like the four inner rocky planets, each one rotates as a rigid body so everything goes at the same angular speed, e.g. 360 degrees in 24 hours for the Earth.

Things get a bit more complicated with the "gas giant" planets (particularly Jupiter and Saturn) which don't rotate as solid bodies.

Their periods of rotation depend on latitude.

Now, consider the Earth. The Earth does rotate as a solid body.

A point at the north or south pole has no linear speed, while a point on the Earth's equator has the maximum linear speed of about 25,000 miles (once round the equator) in 24 hours. At other places on the Earth's surface just multiply by the cosine of the latitude to find the linear speed.

This is the origin of the Coriolis force, which causes cloud systems to rotate.

If you travel north in the northern hemisphere, you are moving towards a more northerly latitude and towards a point with a small linear speed.

This deceleration makes you feel a small force pushing you to the right (actually it's too small to feel) but if you happened to be a piece of cloud you would deviate to the right.
