gravitational orbit
31Graveyard orbit — A graveyard orbit, also called a supersynchronous orbit, junk orbit or disposal orbit, is an orbit significantly above synchronous orbit, where spacecraft are intentionally placed at the end of their operational life. It is a measure performed in …
32Medium Earth orbit — MEO redirects here. For other uses, see MEO (disambiguation). Comparison of GPS, GLONASS, Galileo and Compass (medium earth orbit) satellite navigation system orbits with the International Space Station, Hubble Space Telescope and Iridium… …

34Halo orbit — A halo orbit is a periodic, three dimensional orbit near the L1, L2, or L3 Lagrange points in the three body problem of orbital mechanics. A spacecraft in a halo orbit does not technically orbit the Lagrange point itself (which is just an… …
35Lunar orbit — In astronomy, lunar orbit (also known as a Selenocentric orbit) refers to the orbit of an object around the Moon.As used in the space program, this refers not to the orbit of the Moon about the Earth, but to orbits by various manned or unmanned… …
36Inclined orbit — A satellite is said to occupy an inclined orbit around the Earth if the orbit exhibits an angle other than zero degrees with the equatorial plane. This angle is called the orbit s inclination. Special case: geosynchronous inclined orbit A… …
37Capture orbit — A capture orbit is a reverse escape orbit. It is a parabolic orbit with as special case a straight line in the direction of the center of the central body. If it intersects the central body or its atmosphere the object will crash into the central …
38Escape orbit — An escape orbit (also known as C 3 = 0 orbit) is a high energy parabolic orbit around the central body. A body in this orbit has at each position the escape velocity with respect to this central body, for this position. If this energy were… …
39Gate orbit — Gate orbits are optimal circular departure orbits for transfer from one planet to another. At certain specific orbits around a cosmic body, the additional delta v required to go from orbital velocity to hyperbolic trajectory for an interplanetary …
40osculating orbit — noun The orbit that an astronomical body such as a planet, asteroid, comet or satellite would follow if suddenly all perturbing forces other than the gravitational attraction of the Sun or (for a satellite) its planet were to disappear …
