Here's why:
* Rotation Direction: The direction of a planet's rotation is determined by the way it spins on its axis.
* North Pole Perspective: When we view a planet from its north pole, we are looking down on the top of the planet.
* Counterclockwise Spin: If the planet appears to spin counterclockwise from this perspective, it means the rotation is in the opposite direction of Earth's rotation.
* Retrograde Rotation: Rotation opposite to the direction of most planets in our solar system is called retrograde rotation.
Important Note: The definition of "north pole" is based on the direction of a planet's magnetic field, which is not always aligned with its axis of rotation.
