The earth moves 1667.9239 kilometers per hour around its axis. Because of this, you weigh less on the equator than the poles due to the Coriolis effect. Another thing caused by the Coriolis effect on earth is the deformation of the earth. Because of this, you are farther from the center of the earth on the equator than the poles. The orbital speed of the earth is about approximately 30 (More precisely, 29.80565528) kilometers per second. This causes the earth to perfectly orbit the sun.
