Co Orbital Moon

Pollux, satellite Dione trojan

A moon or satellite co-orbital Trojan is a natural satellite of a planet located around the Lagrangian points L ₄ and L _5, planet-moon system. Thus, a satellite is present on the moon's orbit, unlike a Trojan asteroid that is present on the orbit of the planet.

Seven examples are currently known in the solar system , all in the Saturn system :

Telesto and Calypso orbit of Tethys
Helen and Pollux on the orbit of Dione
