A geosynchronous orbit is one that has the same orbital period as the Earth's sidereal rotation (23 h 56 m 4 sec), but does not have an orbital inclination and eccentricity of zero. A satellite in such an orbit would weave figure-eights around a point on the ecliptic when viewed from the ground. It is often used to mean geostationary orbit and is sometimes also called a Clarke orbit.
