What term is used for astronomical bodies that revolve around larger celestial bodies?

The term used for astronomical bodies that revolve around larger celestial bodies is "satellites." Satellites can be natural, like moons, which orbit planets, or artificial, such as space stations or spacecraft placed into orbit by humans. This term specifically captures the relationship of being in orbit around a larger body, distinguishing them from other celestial entities that may exist independently or in different arrangements.

Planets, while they do revolve around stars, are not considered satellites as they do not orbit another astronomical body like a moon does for a planet. Stars are massive celestial bodies that generate energy through nuclear fusion and are part of larger structures like galaxies. Galaxies themselves are vast collections of stars, gas, dust, and dark matter, rather than individual orbiting bodies. Thus, "satellites" accurately describes those objects in orbital motion around a larger celestial body.
