Encyclopedia

Natural satellite or moon is a celestial body that orbits a planet or smaller body, which is called its primary. The two terms are synonymous for non-artificial satellites of planets, dwarf planets and minor planets. — Wikipedia

Moon, Natural Satellite (Encyclopædia Britannica)

Exomoon or extrasolar moon is a natural satellite that orbits an exoplanet or other non-stellar extrasolar body. It is inferred from the empirical study of natural satellites in the Solar System that they are likely to be common elements of planetary systems. The majority of detected exoplanets are giant planets. In the Solar System, the giant planets have large collections of natural satellites. Therefore, it is reasonable to assume that exomoons are equally common. — Wikipedia
