how fast does the earth spin?
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.

How fast does the Earth spin and why don't we feel it?
Earth moves very fast. It spins ( rotates ) at a speed of about 1,000 miles (1600 kilometers) per hour and orbits around the Sun at a speed of about 67,000 miles (107,000 kilometers) per hour. We do not feel any of this motion because these speeds are constant.
How fast would the Earth have to spin to throw us off?
It works out at about 28,437 km/h (17,670 mph ). The Earth would have to spin once every 84 minutes to achieve that speed at the equator, or about 17 times faster than it actually spins. If you move away from the equator the centrifugal force is lower so you still wouldn't fly off into space, even at that speed.
