The speed of Earth’s rotation varies depending on where you are on the planet:
At the Equator:
The Earth rotates at its fastest speed at the equator. The rotational speed is approximately 1,674 kilometers per hour (1,040 miles per hour).This is calculated by dividing the Earth’s circumference at the equator (~40,075 kilometers or ~24,901 miles) by the time it takes to complete one full rotation (24 hours).
Key points about Earth’s rotation speed:
- Measured at the equator: The fastest rotation speed is measured at the Earth’s equator.
- Decreases with latitude: As you move away from the equator towards the poles, the rotation speed decreases.
- One rotation per day: The Earth completes one full rotation on its axis every 24 hours.
