We canât feel Earthâs rotation or spin because weâre all moving with it, at the same constant speed. Earth spins on its axis once in every 24-hour day. At Earthâs equator, the speed of Earthâs spin is about 1,000 miles per hour (1,600 kph). The day-night has carried you around in a grand circle under the stars every day of your life, and yet you donât feel Earth spinning. Why not?
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.
