  • Planetary Motion: Understanding Prograde Rotation and Orbit
    You're close! Here's a breakdown of the concepts you mentioned:

    * Most planets revolve around the sun in a counter-clockwise direction when viewed from above the Earth's North Pole. This is called prograde motion.

    * Most planets also rotate on their axis in a counter-clockwise direction when viewed from the North Pole. Again, this is called prograde rotation.

    * Most moons also orbit their planets in a counter-clockwise direction (prograde) when viewed from the North Pole.

    It's important to remember that there are exceptions:

    * Venus rotates in a retrograde direction (clockwise) as viewed from the North Pole.

    * Uranus rotates on its side, almost parallel to its orbital plane.

    * Some moons have retrograde orbits around their planets.

    While there are exceptions, the general trend in our solar system is for planets and their moons to revolve and rotate in the same direction (counter-clockwise when viewed from the North Pole). This is likely a result of the way the solar system formed from a spinning disk of gas and dust.
