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?
Most likely, as youâre reading this right now, youâre sitting down, perceiving yourself as stationary. Yet we know â at a cosmic level â weâre not so stationary after all. For one, the Earth rotates on its axis, hurtling us through space at nearly 1700 km/hr for someone on the equator. Thatâs not really all that fast, if we switch to thinking about it in terms of kilometers per second instead.
