What this is. An interactive three-body model of the
Earth–Moon system with solar tidal forcing, in scaled units. It shows why temporary
capture is possible and how fragile it is — it is
not a precision integrator
and will not reproduce a specific object's trajectory.
The default view looks down from ecliptic north, so the Moon and the Sun both
circle counterclockwise, the direction the real ones do.
