Abstract

In order to find a mechanism to explain highly inclined Apollo-Armor asteroids, we integrated over some Myrs the orbital evolutions of asteroids located in the secular resonance ν 16. When the resonant argument Ω - Ω J librates around 180°, the inclination of model asteroids increases from 4° to 24° only. Also, additional passages through the ν 16 secular resonance do not increase the inclinations furthermore. On the other hand, after a temporary passage through the ν 5 resonance, the ν 16 resonance argument Ω - Ω J may librate around 0°. Libration about this new libration center causes further increase of inclination. It appears that the overlapping resonances, ν 5 and ν 16, may produce highly inclined orbits. A backwards integration of the asteroid 2335 James located at present in the ν 16 resonance illustrates the mechanism we propose to produce highly inclined Apollo-Armor asteroids.
