Communication satellites are often placed in geosynchronous orbits, which means that the satellite always appears in the same location relative to a receiver on the ground. This requires among other things that the rotational speed at which the satellite orbits the planet is the same as the rotational speed at which the planet spins on its axis. Consider a planet with mass = 4.32 × 1024 kg and radius = 5.43 × 106 m and rotational period 25.0 hours.
