Planet X and the Extended Scattered Disk

The effects that a hypothetical trans-Plutonian planet would produce on theorbital distribution of the Classical Edgeworth-Kuiper-Belt, has beensurveyed for different physical and orbital parameters of the hypotheticalbody in Melita et al. (2003a). The best fits were obtained by a moderatelyeccentric and inclined Earth-sized object with a semimajor axis of ～ 70AU. However the history of some objects in the `Extended Scattered disk’still represent a puzzle. One possibility is that they can be `extracted’from the Scattered disk by the planetoid. In this work we confirm that such anhypothesis would not explain the present orbit of 2000 CR105, given theconditions for a gap as observed to be formed in the Classical EKB.
