Standing still at almost 1,700 km/h

Almost 1,700 km/h, while standing still on the equator. Earth turns once a day, carrying the ground about 40,000 km around. Its spin also makes the equator bulge about 21 km farther from the center than the poles. That is why Chimborazo, rather than Everest, has the summit farthest from Earth’s center.
