The âcity of loveâ dwarfs Barcelona in size, being incredibly large from one end to the other, particularly so for a European city. The amount of beautiful monuments to see in Paris is overwhelming â from the Louvre to Versailles, my artistic side was more than satisfied.
But how fast does the Earth rotate? You might be surprised to know that a spot on the surface of the Earth is moving at 1675 km/h or 465 meters/second. Thatâs 1,040 miles/hour. Just think, for every second, youâre moving almost half a kilometer through space, and you donât even feel it.
In the case of natural space objects (meteoroids) that orbit around the Sun, these travel at even greater velocities. To remain in its orbit around the Sun, the Earth has to move at 30 km/sec. Other objects that come near the Earth may have relative velocities ranging anywhere from 11 km/sec to 72 km/sec. A 2 mm space debris fragment colliding at 10 km/s is like being hit with a cricket ball at 100 km/hour. 2  A 10 mm fragment at the same speed is like being hit by a large motorbike at 100 km/hour.
