An areostationary orbit (abbreviated ASO) is a circular areosynchronous orbit in the Martianequatorial plane 11,000 km above the surface, any point on which revolves about Mars in the same direction and with the same period as the Martian surface. Although no artificial satellites have been placed so far in this orbit, it is of interest to some scientists forseeing a future telecommunications network for the exploration of Mars. Areostationary orbit is a concept similar to Earth's geostationary orbit. Areosynchronous orbits are class of synchronous orbits for artificial satellites around the planet Mars. ... For the Roman god, see Mars (mythology). ... The equator is an imaginary circle drawn around a planet (or other astronomical object) at a distance halfway between the poles. ... A kilometre (American spelling: kilometer), symbol: km is a unit of length in the metric system equal to 1000 metres (from the Greek words χίλια (khilia) = thousand and μÎÏ„Ïο (metro) = count/measure). ... The orbital period is the time it takes a planet (or another object) to make one full orbit. ... For other uses, please see Satellite (disambiguation) A satellite is an object that orbits another object (known as its primary). ... A telecommunications network is a network of telecommunications links arranged so that messages may be passed from one part of the network to another over multiple links. ... For the Roman god, see Mars (mythology). ... A geostationary orbit (GSO) is a circular orbit directly above the Earths equator (0º latitude). ...

In astrodynamics or celestial mechanics a circular orbit is an elliptic orbit with the eccentricity equal to 0.
It is an example of a rotation around a fixed axis: this axis is the line through the center of mass perpendicular to the plane of motion.
Thus the escape velocity from any distance is √2 times the speed in a circular orbit at that distance: the kinetic energy is twice as much, hence the total energy is zero.
