Venus and Uranus are unique in our solar system because they rotate in the opposite direction of all the other planets, including Earth. This is called retrograde rotation.

Here's a breakdown:

* Most planets rotate counter-clockwise when viewed from above the North Pole. This means they spin in the same direction as the Sun's rotation.

* Venus and Uranus rotate clockwise, which is opposite to the general trend.

The reason for this unusual rotation is still debated among scientists, but it's likely due to massive impacts early in their formation.
