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?
While the Earth orbits around the Sun at a relative 66,700 miles per hour, the Sun is not a stationary object. A widen perspective could include several other facts as well. The earth's rotational speed, depending on how close to the poles varies from 0 to 1040 miles/hour, which at the high end is about .288 miles/sec. This combined with the 66,700 mile/hour mentioned above, is about 18.5 miles/second. It is commonly known that the earth rotates around the sun.
