A satellite in low orbit typically about 800 km from the Earth is exposed to an immense gravitational pull and has to move at considerable speed in order to generate a corresponding centrifugal force. There is a direct connection between the distance from the Earth and the orbital velocity of the satellite. At a distance of 36,000 km, the orbiting time is 24 hours, corresponding to the Earth's rotation time. At this distance, a satellite above the Equator will be stationary in relation to the Earth.
Its distance from the Earth varies between 356,000 and 407,000 km (221,000 and 253,000 miles) in the course of each month; the average distance is 384,400 km (238,900 miles), less than 1% of the distance to Venus and Mars, even at the time of their closest approach.
