Satellite

Satellites, often spacecraft, are objects intentionally placed into orbit around celestial bodies. They serve numerous purposes, including communication, weather forecasting, navigation, broadcasting, scientific research, and Earth observation. Satellites also have military applications such as reconnaissance, early warning systems, and signals intelligence. Defunct satellites and final rocket stages also contribute to the population of objects in space.
