Besides, future dynamical evolution [of suspiciously extra-solar comet 96P/Machholz 1] displays orbital flips when its eccentricity is excited to a high value and its orbit turns over by nearly 180°, rolling over its major axis. This unusual behaviour, that is preserved when post-Newtonian terms are included in the numerical integrations, may also help understand the production of NEOs on retrograde orbits.
post-Newtonian = Using GR in numerical integrations?
