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.
Earth is on the inside track, and so it gets around more quickly. Sometimes itâs close to Mars, when itâs making a pass, and other times itâs far away, at the other side of the track. The minimum distance from the Earth to Mars is about 54.6 million kilometers. The farthest apart they can be is about 401 million km. The average distance is about 225 million km.
