Moon vs. Satellite
A natural body orbiting a planet versus any object (natural or artificial) orbiting another.
The comparisoni
“The GPS satellites in low orbit — "satellite" is the broader term. A MOON is specifically a natural satellite of a planet.”
The ruleii
¶
MOON = natural. SATELLITE = any.
A MOON is a natural satellite of a planet (Earth has one; Jupiter has 95+). A SATELLITE is any object orbiting another, natural or artificial. All moons are satellites; not all satellites are moons.
Memory aidiii
Remember it like this
Every moon is a satellite.
