Do all planets revolve the same way? What makes the earth spin in the direction it spins?
Revolve, as in orbiting the Sun? Yes, they all orbit the Sun in the same direction Earth does. Some comets and asteroids orbit backwards, and some (moreso comets than asteroids) orbit virtually perpendicular to the plane of Earth’s orbit. Rotate, as to spin on ones axis (the thing that causes day and night on Earth)? Earth rotates counter-clockwise, as seen from above Earth’s north pole, the same direction it revolves around the Sun. But two planets (used to be 3, when Pluto was a planet) rotate clockwise – Venus and Uranus. Some might quibble about Uranus, as it spins on its side, but technically it rotates clockwise. Why do they all revolve in the same direction, and most rotate in the same direction? Because of the way the solar system formed. It formed out of a nebula – a giant cloud of gas and dust in space. This cloud had a slight rotation to it. Gravity caused the dust and gas to come together, but since the nebula was spinning, it collapsed into a disk instead of a sphere. The
