With this orientation, all planets in our solar system except Venus and Uranus rotate anticlockwise (counterclockwise) and NOT clockwise. Venus rotates clockwise slowly and Uranus' axis of spin is pushed over to one side so far that is north pole is pointing downwards and therefore its spin is clockwise too. read more
Probably due to major collisions in the early solar system. We found plenty of other evidence of collisions on the moons of the outer planets. read more
All the planets rotate anticlockwise, except one All the planets in the solar system rotate anticlockwise, except one. Venus is the only planet that rotates clockwise. Venus (radius 3,760. 4 miles) is similar to Earth (radius 3,963. 19 miles) in size and structure but spins very slowly; a day on Venus is 243 Earth days long. read more

A planet's axial tilt is a measure of whether the planet is in prograde (the natural direction of rotation of most bodies in our solar system) or retrograde (the opposite, ie, from East to West) rotation. read more
