Almost exactly 1 rotation per 24 hours.
If Earth did not rotate, the celestial poles would align with the geographic poles, and the celestial equator would align with Earth's equator. The celestial poles are points in the sky that the Earth's axis points towards, and the celestial equator is an imaginary line in the sky directly above the Earth's equator. Without Earth's rotation, these references would be fixed in the sky.
The Earth rotates on its axis at a speed of about 1,000 miles per hour (1,600 kilometers per hour) at the equator. As you move towards the poles, this speed decreases.

The Earth rotates at a speed of about 1,000 miles per hour (1,600 kilometers per hour) at the equator. This means that in one hour, the Earth completes one full rotation on its axis.
The Earth would need to rotate at a speed faster than its current rotation, approximately 1100 mph (1700 km/h) at the equator, for humans to noticeably feel the change. However, such a rapid rotation speed would have catastrophic consequences on Earth's ecosystem and atmosphere.
If the Earth did not rotate, global winds would follow a north-south path from the poles to the equator, due to the temperature difference between the poles and the equator. This wind pattern would be known as the Hadley cell circulation.
The planet Earth rotates on its axis exactly once per day.
It can't rotate that fast, since the linear speed at the equator would exceed the speed of light by far. The fastest it could rotate in theory would be about 7 times a second. In that case, it would break apart immediately.
About 1,076.03 feet per second.
the Earth revolves about 23 miles per sec.
About 27 days Since the sun is not solid, it rotates at different rates at different latitudes. One rotation takes 36 days at the poles but only 25 days at the equator.
The earth's circumference at the Equator is 24,902 miles. It makes a complete rotation in 24 hours, so divide the Equator's length by 24. The answer is that, at the Equator, the Earth rotates at 1,037 miles per hour.
