A '''satellite''' is something that orbits around a [[planet]], for example, a [[moon]], or a man-made object that facilitates [[telecommunications]].

A man-made satellite is a [[radio]] relay station that orbits the [[eart]]h. A complete satellite communications system also includes [[earth]] stations that communicate with each other via the satellite. The satellite receives a signal transmitted by an originating earth station and retransmits that signal to the destination earth station(s). Satellites are used to transmit telephone, television and data signals originated by common carriers, broadcasters and distributors of cable [[television]] program material.
