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 migrant toward the external part of the Solar System. Some of them are ejected from the Solar System with a great e. Of the test particles studied less than 10 cases becoming Earth and Mars crossers. Many objects make numerous close approaches to Jupiter and Saturn. Other clones, a few, can reach the region a approx 500 AU, e approx 0.78, i approx 15° like Sedna. This behavior of some clones occur when Neptune has a = 28 AU.
