Scientific paper
The orbits of three postulated nu5 secular resonant asteroids, (582) Olympia, (945) Barcelona and (1580) Betulia (Williams, 1979) have been numerically integrated over timescales of the order of 1 Myr in the Sun-Jupiter-Saturn model. Olympia and Barcelona represent the nu5 resonance region near 2.6 AU. This resonance region does not yield Mars-crossers on Myr timescales. The nu5 region near 2.2 AU, the region of the Amor asteroid Betulia, may yield highly inclined Apollo asteroids. Orbits entering this resonance region with eccentricities of 0.3 and inclinations of 22 deg can be transformed into orbits with inclinations up to 70 deg and eccentricities up to 0.7.
