Abstract
We have analyzed the dynamical behavior of objects located in a position 22 < a < 26 AU which corresponds to the mean motion resonances 3:2 and 2:3 with Neptune and Uranus respectively. Mostly of the studied objects migrate toward the external part of the Solar System, called Kuiper belt, a scattered disk in the a > 30 AU region. Some are ejected from the Solar System with e=∞. Of the test particles studied, less than 10% migrate toward the inner part, in some cases becoming Earth and Mars crossing. This fact may be a source of near-Earth objects (NEOs), as asteroids in the Main Belt lying near the 3:1 resonance with Jupiter. Many objects make numerous close approaches to Jupiter and Saturn. Other clones, a few, can reach the region a ∼ 500, e ∼ 0.78, i ∼ 15° (Sedna: a = 509 AU, e = 0.851, i = 11.9). This behavior of some clones occur when Neptune has a = 28 AU.
