How fast does Earth rotate on its axis?
Answer
1,600 km/h
At the equator, Earth rotates at approximately 1,670 km/h (1,040 mph), completing one full rotation every 24 hours. This rotational speed decreases toward the poles, where the rotational velocity approaches zero at the North and South Poles. This rotation is what creates the apparent movement of the Sun and stars across the sky and is fundamental to life's circadian rhythms.
💡 Did you know?
Because Earth's rotation is constant, and everything (including the atmosphere) is moving together at the same speed, we do not perceive the motion.

- 500 km/h
- 1,000 km/h
