Noun

Trojan moon ‎(plural Trojan moons)

1. (astrophysics) a pseudo-moon that occupies a Trojan point of a system

Usage notes

This is a pseudo-moon, as it does not actually orbit the secondary of the system, but rather, it orbits the primary of the system. If the secondary is a planet, it may be referred to as a moon of the planet, or as a planet or minor body of the star primary. If the secondary is a moon, it may be referred as the moon of a moon, or the moon of the planet primary.
