  We suppose that some large trans-Neptunian objects could be formed directly
by the compression of rarefied dust condensations of the protoplanetary disk,
but not by the accretion of smaller planetesimals. 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.
