A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately $35,800$ kilometers $(22,300$ miles) directly over the equator, that revolves in the same direction the earth rotates (west to east).

At this altitude, one orbit takes $24\, hrs,$ the same length of time as the earth requires to rotate once on its axis.
