text: The moon has a nearly circular orbit around Earth’s center of mass and has what is called a bound rotation with earth.
text: The orbit of the Moon is a nearly circular ellipse about the Earth (the semimajor and semiminor axes are 384,400 km and 383,800 km, respectively: a difference of only 0.16%).
text: Both moons have very circular orbits which lie almost exactly in Mars's equatorial plane, and hence a capture origin requires a mechanism for circularizing the initially highly eccentric orbit, and adjusting its inclination into the equatorial plane, most probably by a combination of atmospheric drag and tidal forces, although it is not clear that sufficient time is available for this to occur for Deimos.
text: A big drawback of this explanation is that the moon’s orbit is almost circular and cyclical.

text: With an orbital eccentricity of only 0.009, the orbit itself is nearly circular, and the orbital inclination relative to Jupiter's equatorial plane is small, at 0.470°.

text: A satellite in a synchronous orbit that is both equatorial and circular will appear to be suspended motionless above a point on the orbited planet's equator.
text: A synchronous orbit around Earth that is circular and lies in the equatorial plane is called a geostationary orbit.
text: The more general case, when the orbit is inclined to Earth's equator or is non-circular is called a geosynchronous orbit.
text: First, he found that the orbits of the planets in our Solar System are elliptical, not circular (or epicyclic), as had previously been believed, and that the Sun is not located at the center of the orbits, but rather at one focus.
