DRO is a family of stable orbits around a secondary body in a three body system. Recently famous for being used by Orion spacecraft in the Artemis I mission.
In this video, I placed several test particles around the moon with opposite velcoity vector (retrograde - cyan; prograde - orange) to show that orbits are stable only if the particles are moving in retrograde orbits.
I adpoted the inital condition from Turner, G. Results of Long-Duration Simulation of Distant Retrograde Orbits. Aerospace 2016, 3, 37.
