How fast is the earth traveling through space?

Fast!). But we can't just add this to Earth's speed around the Sun, because we're moving in circles – all we can say is that Earth's speed around the galaxy is somewhere between 721,000 km/h and 935,000 km/h depending on the day of the year. read more

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. read more

Finally, there is the motion of the Local Group in the Local Supercluster. This speed is about 600 km/s. Adding all the above motions (0.5 + 30 + 230 + 40 + 600 km/s), we determine how fast is the Earth traveling through space. This comes to around 900 km/s. read more
