About 0.0015 of former Jupiter-crossing objects can get orbits with aphelia inside Jupiter's orbit (mainly less than 4.7 AU) during more than 1 Myr. A considerable portion of near-Earth objects could have come from the trans-Neptunian belt.2 pages, Abstracts of the Conference ''Celestial Mechanics - 2002: Results and Prospect'' (10 -14 September 2002, St. Petersburg, Russia), Institute of Applied Astronomy of Russian Academy of SciencesAstrophysicstext
