In fact: Earth spins on its axis once in every 24-hour day. At Earth’s equator, the speed of Earth’s spin is about 1,000 miles per hour (1,600 km per hour). This day-night spin has carried you around under the sun and stars every day of your life. And yet you don’t feel Earth spinning. Why not? It’s because you and everything else including Earth’s oceans and atmosphere are spinning along with the Earth at the same constant speed.

“Think about riding in a car or flying in a plane. If the ride is going smoothly, you can almost convince yourself you’re not moving. A jumbo jet flies at about 500 miles per hour (about 800 kph), or about half as fast as the Earth spins at its equator. But, while you’re riding on that jet, if you close your eyes, you don’t feel like you’re moving at all. And when the flight attendant comes by and pours coffee into your cup, the coffee doesn’t fly to the back of the plane. That’s because the coffee, the cup and you are all moving at the same rate as the plane.”

“Breaking it down mathematically, the circumference of the Earth at the equator is roughly 40,000 kilometers (24,855 miles), and of course the time that it takes for the Earth to complete one rotation is 24 hours. Because speed equals distance divided by time, an object situated at the equator is moving at a rate of about 1,667 kilometers per hour (1,036 miles per hour).

“The Earth is always in motion. Although it seems like we are standing still on the Earth’s surface, the Earth is spinning on its axis and orbiting the sun. We can’t feel it because it’s a constant motion, just like being in an airplane. We are moving at the same rate as the plane, so we don’t feel like we’re moving at all.”

“Consider the movement of the earth’s surface with respect to the planet’s center. 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.”
