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.
Back to our lunch discussion: How fast, we wondered over our kebabs, would a geostationary satellite have to be moving to stay stationary in the sky? The space shuttle orbiter, we know, orbits at around 8,000 meters per second (18,000 miles per hour) but it does a complete orbit in about 90 minutes. Would a geostationary satellite be going faster or slower? To find out, I did a little math.
