natural satellite
Planet's natural companion
A natural satellite is an astronomical body that orbits a planet or other larger body, held in place by gravitational attraction.
The moon is Earth's natural satellite.
The term distinguishes celestial objects from artificial satellites—spacecraft placed in orbit by humans.
Most planets in our solar system have natural satellites; Jupiter and Saturn have dozens.
