gravitational orbit
11Gravitational well — In physics, a gravity well is the gravitational potential field around a massive body (a particular kind of potential well). Physical models of gravity wells are sometimes used to illustrate orbital mechanics. Gravity wells are frequently… …
12gravitational radiation — ▪ physics the transmission of variations in the gravitational field as waves. According to general relativity (relativity), the curvature of space time is determined by the distribution of masses, while the motion of masses is determined by the… …
13Orbit 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… …
14Orbit — A balance between a ships tendency to fly off into space, inertia, and the gravitational pull of a planet. This allows a ship or satellite to rotate around a planet without using a propulsion system, once it has the proper altitude and speed …

15Kepler orbit — Gravitational attraction is the force that makes the Solar system stick together with the planets orbiting the Sun and the Moon orbiting the Earth. Isaac Newton formulated the physical law for this gravitational attraction which explained Kepler… …
16Geostationary orbit — Geostationary orbit.To an observer on the rotating Earth (fixed point on the Earth), the satellite appears stationary in the sky. A red satellite is also geostationary above its own point on Earth. Top Down View …
17Elliptic orbit — A small body in space orbits a large one (like a planet around the sun) along an elliptical path, with the large body being located at one of the ellipse foci …
18Geosynchronous orbit — A geosynchronous orbit is an orbit around the Earth with an orbital period matching the Earth s sidereal rotation period [V. Chobotov, ed., (1996) Orbital Mechanics, 2nd edition , AIAA Education Series, p. 304.] . This synchronization means that… …
19Timeline of gravitational physics and relativity — Timeline of gravitational physics and general relativity* 800s Ja far Muhammad ibn Mūsā ibn Shākir hypothesizes that the heavenly bodies and celestial spheres are subject to the same laws of physics as Earth, unlike the ancients who believed that …
20Standard 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… …
