orbital parameter
1Orbital 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… …
2Orbital 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… …
3Orbital perturbation analysis (spacecraft) — Isaac Newton in his Philosophiæ Naturalis Principia Mathematica demonstrated that the gravitational force between two mass points is inversely proportional to the square of the distance between the points and fully solved corresponding two body… …
4Orbital 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 …
5Orbital 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… …
6Orbital eccentricity — This article is about eccentricity in astrodynamics. For other uses, see Eccentricity (disambiguation). An elliptic Kepler orbit with an eccentricity of 0.7 (red), a parabolic Kepler orbit (green) and a hyperbolic Kepler orbit with an… …
7Orbital plane (astronomy) — All of the planets, comets, and asteroids in the solar system are in orbit around the Sun. All of those orbits line up with each other making a semi flat disk called the orbital plane. The orbital plane of an object orbiting another is the… …
8Specific orbital energy — In the gravitational two body problem, the specific orbital energy (or vis viva energy) of two orbiting bodies is the constant sum of their mutual potential energy ( ) and their total kinetic energy ( ), divided by the reduced mass. According to… …
9Standard gravitational parameter — In astrodynamics, the standard gravitational parameter mu of a celestial body is the product of the gravitational constant G and the mass M::mu=GM The units of the standard gravitational parameter are km3s 2mall body orbiting a central bodyUnder… …
10Tisserand's parameter — In Celestial Mechanics, Tisserand’s parameter (or Tisserand s invariant) is a combination of orbital elements used in a restricted three body problem.DefinitionFor a small body with semimajor axis a,!, eccentricity e,!, and inclination i,!,… …
