Satellite vs. Moon — What's the Difference?
By Tayyaba Rehman — Updated on November 3, 2023
A satellite is any object that orbits a planet, while a moon is a natural satellite specifically orbiting a planet. Satellites can be man-made or natural; moons are always natural.

Key Differences
A satellite is a general term for any object that orbits around a larger body in space; this includes both man-made objects like communications satellites and natural objects like moons. The word "moon," however, is used exclusively to describe natural satellites that orbit planets.
Satellites can vary widely in their purpose and design, especially when considering artificial satellites, which are used for communication, weather monitoring, and scientific research. Moons, in contrast, are natural celestial bodies that have formed from the accumulation of space debris in the orbit of a planet, often playing key roles in affecting that planet's tides and sometimes its climate.
In terms of nomenclature, satellites are named based on their function or the mission they are a part of, such as the Hubble Space Telescope. Moons are usually named after mythological characters or figures from the history of astronomy, like Jupiter's moons Ganymede and Callisto.
The function of satellites can be quite diverse: some satellites are designed to observe Earth, others are meant for deep space exploration. Moons, however, do not have a designed function but can be studied to understand more about planetary formation and the conditions of their respective planets.
While all moons are satellites by definition, not all satellites are moons. Satellites include a broad category of man-made and natural objects in orbit, while the term "moon" is a specific subtype within that broad category, referring to a certain kind of natural satellite.
