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 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 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… … 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 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… … 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
Specific 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… … Wikipedia
