AI overview
An artificial satellite is a human-made object launched into space that orbits Earth or other celestial bodies. Satellites matter because they enable critical services like weather forecasting, GPS navigation, telecommunications, and scientific research about our planet and universe.

A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation (GPS), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning, signals intelligence and, potentially, weapon delivery. Other satellites include the final rocket stages that place satellites in orbit and formerly useful satellites that later become defunct.
