Orbital resonance — For the science fiction novel by John Barnes, see Orbital Resonance (novel). In celestial mechanics, an orbital resonance occurs when two orbiting bodies exert a regular, periodic gravitational influence on each other, usually due to their… … Wikipedia
Orbital elements — are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are generally considered in classical two body systems, where a Kepler orbit is used (derived from Newton s laws of motion and Newton s law… … Wikipedia
Orbital inclination change — is an orbital maneuver aimed at changing the inclination of an orbiting body s orbit. This maneuver is also known as an orbital plane change as the plane of the orbit is tipped. This maneuver requires a change in the orbital velocity vector… … Wikipedia
Longitude Du Nœud Ascendant — Diagramme des éléments orbitaux, incluant la longitude du nœud ascendant (Ω). En mécanique céleste, la longitude du nœud ascendant est un élément orbital permettant de définir l orbite d un corps autour d un autre. Pour un corps en orbite autour… … Wikipédia en Français
Longitude du noeud ascendant — Longitude du nœud ascendant Diagramme des éléments orbitaux, incluant la longitude du nœud ascendant (Ω). En mécanique céleste, la longitude du nœud ascendant est un élément orbital permettant de définir l orbite d un corps autour d un autre.… … Wikipédia en Français
Orbital state vectors — In astrodynamics or celestial dynamics orbital state vectors (sometimes state vectors) are vectors of position ( ) and velocity ( ) that together with their time (epoch) ( ) uniquely determine the state of an orbiting body. State vectors are… … Wikipedia
Longitude of the ascending node — The longitude of the ascending node (☊ or Ω) is one of the orbital elements used to specify the orbit of an object in space. It is the angle from a reference direction, called the origin of longitude , to the direction of the ascending node,… … Wikipedia
Orbital mechanics — A satellite orbiting the earth has a tangential velocity and an inward acceleration. Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other… … Wikipedia
Orbital speed — Not to be confused with Escape Velocity. The orbital speed of a body, generally a planet, a natural satellite, an artificial satellite, or a multiple star, is the speed at which it orbits around the barycenter of a system, usually around a more… … Wikipedia
Orbital period — For the music album, see Orbital Period (album). The orbital period is the time taken for a given object to make one complete orbit about another object. When mentioned without further qualification in astronomy this refers to the sidereal period … Wikipedia
Orbital station-keeping — In astrodynamics orbital station keeping is a term used to describe the orbital maneuvers made by thruster burns that are needed to keep a spacecraft in a particular assigned orbit. For many Earth satellites the effects of the non Keplerian… … Wikipedia
