What would happen if the world stopped spinning?
Have you ever wondered what would happen if the world stopped spinning? The consequences would be cataclysmic, right? Well, not necessarily. It all depends on the speed with which the planet came to a stop. A sudden and abrupt halt? Forget it! But if the world slowed on its axis gradually and came safely to a standstill, then life on Earth might just survive. But here's the thing: the rotation of the Earth is already slowing down. So, what's going to happen?

What is the Earth's rotation?
Answer: the rotation of Planet Earth around its own axis. The Earth rotates at around 1,600 km/h (1,000 mph).

At what speed does the planet spin?
This figure is based on the fact that our planet's circumference is roughly 40,075 km (24,901 mi). Thus, the surface of the Earth at the equator moves at a speed of 460 meters per second—or roughly 1,000 mph.

How long?
Earth rotates once in about 24 hours. In fact, once every 23 hours, 56 minutes, and 4.09053 seconds, to be precise.

Spinning in time
You can't feel the Earth spinning. That's because you and everything else—including the planet's oceans and atmosphere—are spinning along with the Earth at the same constant speed. Read More…
