How Fast Is Earth Moving?

Even though we always feel that the ground beneath our feet is still, the earth is actually rotating constantly. We are all aware of the fact that the Earth is the centre of everything, and retrograde motion occurs when the Earth is interacting with another planet in the orbit.

How fast does the Earth spin?

The Earth is constantly spinning, and this speed depends on the latitude of your location. NASA reveals that the speed around the equator is around 1,037 mph, which makes 1,670 km/h.

On other latitudes, the movement is not quite as fast. The speed tends to decrease towards the Northern or Southern poles. Spaces agencies, such as the International Space Station, seek benefits from this spin, for instance, the equator is the most preferred location for sending cargo missions.

How fast does the Earth orbit the sun?

The orbital speed of the earth around the sun is around 67,000 mph. This speed can be calculated by examining how fat the Earth travels, and trace out the circumference of the Earth’s orbit. The distance from the Earth to the sun is referred to as an astronomical unit, and it is 149, 597 870 kilometres. So, in one year, the Earth travels for around 584 million miles.

Other Movements in the Galaxy…

The sun has its very own orbit within the Milky Way, and it is nearly 25,000 lights away from the centre of the galaxy. Scientists report that the sun and the solar system are moving at the speed of 200 kilometres per second, and the average speed is 448,000 mph.

The Milky Way, which is 100,000 light years away from the galaxy, also moves in space. It takes the Milky Way around 4 billion years to meet the Andromeda Galaxy, its closest neighbour.

What if the Earth Cease to Spin?

The gravity of the Earth is stronger than its spinning motion, and at the strongest point, being the equator, the spinning motion counters the gravity by a mere 0.3%. NASA reports that there is simply no possibility of the Earth to ever stop spinning. However, in the instance the Earth did suddenly stop spinning, it would cause awful devastation.

The atmosphere would continue to move at the speed of Earth’s rotation, and this would destroy everything from the land, including humans, animals, trees, soil, mountains, and rocks, infrastructure-basically everything. However, if the earth stopped spinning gradually, over a period of time like billions of years, the inhabitants of Earth will have plenty of time to adapt to this gradual change.

  • What does this even mean? The galaxy is 100,000LY away from the galaxy?!?

    This is not true... Maybe to stop spinning SUDDENLY, but we now know that all orbiting bodies tend to tidally lock.
