Velocity of Altitude

[sillysally]

I may have velocity of altitude somewhere in my subconscious because I dreamt I saw a diagram of it. But when it's put into a picture, does it look like a triangle?

I googled it and sure enough it exists but I want to know more about it if anyone can tell me.

This is likely similar to some of the stuff you googled, Sally. Maybe one of our science fellas will come along to help out.

The orbital velocity of the satellite depends on its altitude above Earth. The nearer Earth, the faster the required orbital velocity. At an altitude of 124 miles (200 kilometers), the required orbital velocity is just over 17,000 mph (about 27,400 kph). To maintain an orbit that is 22,223 miles (35,786 km) above Earth, the satellite must orbit at a speed of about 7,000 mph (11,300 kph). That orbital speed and distance permits the satellite to make one revolution in 24 hours. Since Earth also rotates once in 24 hours, a satellite at 22,223 miles altitude stays in a fixed position relative to a point on Earth's surface. Because the satellite stays right over the same spot all the time, this kind of orbit is called "geostationary." Geostationary orbits are ideal for weather satellites and communications satellites.

You're not planning on making a break for it, now, are you Sally?

Everyone knows this is a prison planet.....

Haha, I'll settle for a weekend at Disney World.

Maybe I spent too much time at the TOE the past couple days, I am having creepy technology dreams.
