Question

Geostationary satellite orbits Earth with period equal to:

RankGuru · Accepted Answer

A geostationary satellite is placed in a circular orbit (called the Clarke orbit) roughly 35,786 km above the equator. For the satellite to remain stationary relative to a point on the Earth's surface, its orbital period must exactly match the Earth's rotational period around its axis, which is approximately **24 hours** (specifically one sidereal day). This allows ground antennas to point at a fixed location in the sky without needing complex tracking mechanisms.
