Shows Miorita-like NEAs are stabilized yet Sunward-driven by concurrent Lidov–Kozai and Jupiter-controlled apsidal secular resonances.
The work maps the dynamical setting of NEA 622577 Miorita and identifies a small “flock” of near-Earth asteroids with similar secular behavior. It reports that Miorita experiences a von Zeipel–Lidov–Kozai secular resonance together with a near-apsidal resonance, both controlled by Jupiter, and that this concurrent-resonance configuration can protect objects from inner-planet collisions while still enabling evolution toward low-perihelion, comet-like, potentially Sun-impacting trajectories. The paper highlights an active pathway that can inject NEAs into metastable, Sun-grazing states, and notes that the NEOMOD 3 population model assigns a low probability to such objects.
Direct N-body integrations of orbital evolution, complemented by checks against the NEOMOD 3 orbital distribution model and INT observations.
Celestial mechanics of NEA dynamics, especially secular resonances including von Zeipel–Lidov–Kozai and apsidal resonance concepts.
