We canât feel Earthâs rotation or spin because weâre all moving with it, at the same constant speed. Earth spins on its axis once in every 24-hour day. At Earthâs equator, the speed of Earthâs spin is about 1,000 miles per hour (1,600 kph). The day-night has carried you around in a grand circle under the stars every day of your life, and yet you donât feel Earth spinning. Why not?
The speed of rotation of earth about its axis is 1670 km/hr or 0.4638889. While the speed of revolution of earth around the Sun is 107,000 km/hr or 30 km/s. Well, you can say that when Earth is alone it enjoys solitude, but when itâs around Sun itâs really in a haste. You can calculate these figures easily knowing these values: Circumference of the Earth at the Equator = 40,000 kilometers
