π Planet Rotation Speed
How fast does the ground move beneath you at the equator?
Results
- Equatorial speed
- 1,672.52 km/h
- Equatorial speed for a spherical planet.
How it works
v = 2ΟR / T
Earth's equator moves at about 1,670 km/h β faster than the speed of sound. You do not feel it because everything around you, including the air, moves with it.
Assumptions: Spherical planet, equatorial speed.
