17,000 mph!

At the equator the earth spins at just over 1,037 miles per hour. The 17kmph low earth orbit, in the opposite direction of the earths rotation, gives you one rotation every 90min. But in a geostationary orbit satellites that remains stationary over the same spot on earth. How fast do they travel?

Another one to blow your mind... we are all in free fall into the sun. In fact, everything in the solar system is free falling towards the sun. The only reason we haven't hit the sun yet is because our angular momentum allows us to miss it over and over again.

Did you know you and everyone on this planet are traveling at approx 1,000 MPH? That's how fast Earth spins. Crazy when you think about it.

how about when we're traveling the same direction earth is spinning?..lol

I had to do some googling


Geosynchronous Orbital distance from "sea level" 35,786 km
Distance of orbit ~165000 mi @ 35,786 km
165000/24 hrs gives you an estimate of 6700 mph

The real calculated value is closer to 6876 mph but the estimate is pretty close.

At the equator its 1037.5646 mph

But at the South & North poles its zero MPH, I bet it makes you dizzy though.......

Just for the record I'm not a nerd, had to google all this stuff........
