1Orbit portrait — In mathematics, an orbit portrait is a combinatorial tool used in complex dynamics for understanding the behavior of one complex dimensional quadratic maps. In simple words one can say that it is : a list of external angles for which rays… …
2orbit — [ôr′bit] n. [MFr orbite < ML orbita < L, path, track < orbis, a circle, wheel] 1. the bony cavity containing the eye; eye socket 2. [L orbita] a) the actual or imaginary path taken by a celestial body during its periodic revolution… …
3Orbit equation — In astrodynamics an orbit equation defines the path of orbiting body around central body relative to , without specifying position as a function of time. Under standard assumptions, a body moving under the influence of a force, directed to a… …
4Orbit Award — The Orbit Awards were given by the National Space Society and the Space Tourism Society to pioneers in the private space travel industry, and presented at the Annual International Space Development Conference The actual award is a holographic… …
5Osculating orbit — In astronomy, and in particular in astrodynamics, the osculating orbit of an object in space (at a given moment of time) is the gravitational Kepler orbit (i.e. ellipse or other conic) that it would have about its central body (corresponding to… …
6Geostationary transfer orbit — A Geosynchronous Transfer Orbit or Geostationary Transfer Orbit (GTO) is a Hohmann transfer orbit around the Earth between a low Earth orbit (LEO) and a geosynchronous orbit (GEO). It is an ellipse where the perigee is a point on a LEO and the… …
7osculating orbit — noun (astronomy) An ellipse whose elements represent the actual position and velocity of a comet at a given moment (the epoch of osculation) • • • Main Entry: ↑osculant …
8Science and mathematics from the Renaissance to Descartes — George Molland Early in the nineteenth century John Playfair wrote for the Encyclopaedia Britannica a long article entitled ‘Dissertation; exhibiting a General View of the Progress of Mathematics and Physical Science, since the Revival of Letters …
9Mean longitude — In astrodynamics or celestial dynamics, mean longitude is the longitude at which an orbiting body could be found if its orbit were circular, and free of perturbations, and if its inclination were zero. Both the mean longitude and the true… …
10Vulcan (hypothetical planet) — Vulcan was a small planet proposed to exist in an orbit between Mercury and the Sun in a 19th century hypothesis. This hypothesis has now been rendered obsolete by Albert Einstein s theory of general relativity.Argument for Vulcan s existenceIn… …
