This is an image of the Earth showing polar and geostationary orbits. The trajectory of a polar orbiting satellite is indicated with a blue line. The trajectory of a geostationary orbit is indicated with an orange line. The polar orbit runs from the north pole to the south pole. The geostationary orbit runs at a higher orbit centred on the equator.
