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 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 forcing — is the effect on climate of slow changes in the tilt of the Earth s axis and shape of the orbit (see Milankovitch cycles). These orbital changes change the total amount of sunlight reaching the Earth by up to 25% at mid latitudes (from 400 to 500 … Wikipedia
Orbital (The Culture) — Orbital illustration, with no apparent Hub In Iain M. Banks fictional Culture universe, an Orbital (sometimes also simply called an O or a small ring) is a purpose built space habitat forming a massive ring (though much smaller than a ringworld)… … Wikipedia
Earth to orbit — (ETO) describes the process or means of placing a payload into an orbit around the Earth. Traditionally this has used rockets, however ETO can also include much more exotic forms of transportation such as railguns and hypersonic cannons and Space … 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
Orbital decay — is the process of prolonged reduction in the altitude of a satellite s orbit. This can be due to drag produced by an atmosphere due to frequent collisions between the satellite and surrounding air molecules. The drag experienced by the object is… … Wikipedia

Orbital tuning — refers to the process of adjusting the time scale of a geologic or climate record so that the observed fluctuations correspond to the Milankovitch cycles in the Earth s orbital motion. Because changes in the Earth s orbit affect the amount and… … Wikipedia
