satellite - Computer Definition
From the Latin satelles, meaning attendant. 1. A attendant celestial body that revolves or is intended to revolve around a larger celestial body. For example, a planet orbits a sun and a moon orbits a planet. The Earth's moon orbits the Earth. Actually, that's not quite true. The moon and the Earth orbit each other as they both revolve around their common center of gravity. As the Earth is the larger of the two and, therefore, exerts more gravitational force, the moon does most of the revolving. 2. A manmade object that orbits the Earth or some other celestial body. Satellites in Geosynchronous Earth Orbit (GEO) are placed in orbital slots such that they maintain their positions relative to the Earth's surface. Medium Earth Orbiting (MEO) and Low Earth Orbiting (LEO) satellites do not. See also GEO, LEO, and MEO.
satellite - Cultural Definition
Any object in orbit about some body capable of exerting a gravitational (see gravitation) force. Artificial satellites in orbit around the Earth have many uses, including relaying communication signals, making accurate surveys and inventories of the Earth's surface and weather patterns, and carrying out scientific experiments.
In politics, a nation that is dominated politically by another. The Warsaw Pact nations, other than the former Soviet Union itself, were commonly called satellites of the Soviet Union.
satellite - Medical Definition
- A minor structure accompanying a more important or larger one.
- A short segment of a chromosome separated from the rest by a constriction, typically associated with the formation of a nucleolus.
- A colony of microorganisms whose growth in culture medium is enhanced by certain substances produced by another colony in its proximity.
satellite - Science Definition
- A small body in orbit around a larger body. See Note at moon.
- An object launched to orbit Earth or another celestial body. Satellites are used for research, communications, weather information, and navigation. The first artificial Earth satellite was Sputnik 1, launched by the Soviet Union in October 1957; the first successful American satellite was launched in January 1958.
Communications satellites receive, amplify, and transmit radio signals between dish antennas that may be hundreds of miles apart.
