They complete exactly one rotation per day.
Low earth orbit low earth orbit leo a low earth orbit leo is as the name suggests an orbit that is relatively close to earth s surface.
A few space probes have been placed into orbit around other bodies and become artificial satellites to the moon venus mars jupiter and saturn.
There are different types of tether satellites including skyhooks format flying tethers momentum exchange tethers and electrodynamic tethers.
Satellites are used for a large number of purposes.
Heo highly elliptical orbit geo stationary earth orbit.
A satellite with a low inclination can use the earth s rotation to help boost it into orbit.
Tether satellites are mainly used for altitude control stabilization propulsion maintaining relative positions of a larger spacecraft sensor system and momentum exchange.

Hence three such synchronous satellites are required to cover the entire earth.
There are 4 types of orbits they are.
Orbits are categorized by its altitude inclination with reference to the equatorial plane eccentricity synchronization parameters planet centered pseudo orbit and others.
Satellites in a highly inclined orbit such as a polar orbit take more energy than a satellite that circles the earth over the equator.
It is normally at an altitude of less than 1000 km but could be as low as 160 km above earth which is low compared to other orbits but still very far above earth s surface.
Satellites can be classified based on their applications orbit in which they are placed.
