satellite
Synonym discussion
Sense: noun/1
While all four words describe objects sent into space, they differ in purpose and orbit. A 'satellite' is any object — natural or artificial — that orbits a larger body; in everyday use it refers to communication or observation devices circling Earth. A 'spacecraft' is a broader term for any vehicle designed for space travel; it may dock at a station, land on a planet, or fly through space without ever entering orbit. An 'orbiter' is a specific type of spacecraft sent to circle a particular body, such as Mars or the Moon, to study it over time — it is always artificial and always in orbit. A 'probe' is sent to gather data from a target, often flying past it or landing on it rather than staying in orbit. For example, a weather 'satellite' orbits Earth continuously, while the Mars 'orbiter' circled the red planet, and the Voyager 'probe' flew past Jupiter on its way out of the solar system.

Etymology
The word 'satellite' comes from Latin 'satelles' (meaning 'attendant' or 'bodyguard'), because early astronomers thought of moons as 'attendants' that followed their planets through the sky. The sense was first used in English around the 1550s for natural moons. After the launch of Sputnik in 1957, the word expanded to cover human-made space devices as well.
