What is the effect of gravity on a satellite?

Question asked by: knowitall

Gravity will keep a satellite in orbit. Without gravity there would be nothing pulling the satellite down and keeping it in orbit around a planet.

For instance if there was no gravity exerted by the earth then the moon would have gone off into space long ago - as it is the earth is slowly losing the moon and it is getting progressively further and further away and eventually would be lost completely by the earth as a satellite.

In addition: Most sattalites are set at parking orbit. I.e same speed(revolution per second) with the earth itself.
