How long does it take for the Earth to spin once? A: Earth makes a complete rotation every 24 hours. The Earth spins at 1,036 miles per hour at the equator while remaining near stationary at the poles. Full Answer >
The Earth rotates (spins) counter-clockwise as viewed from above the North Pole, which is also from above the ecliptic plane of the solar system. This is the arbitrary up and down convention that allows us to say which direction the Earth is spinning. Most other objects in the solar system spin and orbit counter-clockwise as well. Depending on your location on the planet, the Earth's spin (west to east) could be seen as clockwise or counter-clockwise. In the Northern Hemisphere, looking south toward the equator, the Earth turns counter-clockwise.
