Do Satellites Move Faster Than The Earth

Orbiting twice a day instead of the once of a geostationary satellite mean lower passes.

Do satellites move faster than the earth.

At an altitude of 124 miles 200 kilometers the required orbital velocity is a little more than 17 000 mph about 27 400 kph. This slows down gps satellite clocks by a small fraction of a second similar to the airplane example above. Your spacecraft will travel away from the earth and be slowed by gravity but the gravitational pull of the earth drops so rapidly that it will never stop you entirely. The nearer to earth the faster the required orbital velocity.

Your spacecraft will leave. A satellite maintains its orbit by balancing two factors. At the zenith they move 1 4 and 0 4 degrees per second respectively and drop a factor of 10 in rate or more as they approach the horizon. Gps satellites orbit around earth at about 8 700 miles 14 000 kilometers per hour.

Looking at satellites between 300 and 1000 km altitude that happen to pass overhead they definitely move the fastest when overead and slow way down. At this altitude the speed of a satellite s rotation around the world is identical to the. Satellites move faster than the earth. Furthermore faster orbits e g.

Counterintuitively a satellite closer in from geostationary orbit must travel faster than the earth s surface in order to stay aloft to keep missing the earth as the lower altitude causes it to fall faster toward it by the inverse square law. Communications satellites also travel faster because they are. Its velocity the speed it takes to travel in a straight line and the gravitational pull that earth has on it. Gps satellites orbit around earth very quickly at about 8 700 miles 14 000 kilometers per hour.

After 6 months on the international space station iss orbiting earth at a speed of about 7 700 m s an astronaut would have aged about 0 005 seconds less than those on earth. With current technology severely limiting the velocity of space travel however the differences experienced in practice are minuscule. The orbital velocity of the satellite depends on its altitude above earth.
