How fast does the Earth move?

Earth is constantly moving. As it zooms around the sun, Earth also spins on its axis, like a basketball on the tip of a player's finger.

So, how fast is Earth moving? In other words, how fast is it rotating on its axis and how fast is it orbiting the sun? To go even further, how fast is the solar system orbiting the Milky Way galaxy?

Now that your head is spinning just like Earth, let's start with the planet itself. Earth turns on its own axis about once every 24 hours (or, to be precise, every 23 hours, 56 minutes and 4 seconds). Earth measures 24,898 miles (40,070 kilometers) in circumference, so when you divide distance by time, that means the planet is spinning 1,037 mph ( 1,670 km/h). Meanwhile, Earth orbits the sun at about 67,000 mph (110,000 km/h), according to Ask an Astronomer, a blog run by astronomers at Cornell University in Ithaca, New York. Scientists know that by taking the distance Earth travels around the sun and dividing it by the length of time Earth takes to complete one orbit (about 365 days).
