The elements below for 1999 CB119, CC119, CD119, CF119, CG119, CH119,
CJ119 and CK199 are from assumed circular orbits, the column headed Peri.
in fact giving the argument of the latitude. The fourth entry, for 1999 CE119,
is an assumed perihelic 4:5 Neptune librator. This is very hypothetical,
since no object of this type has yet been demonstrated, but this solution
was more successful than others at avoiding encounters with Neptune, in that
it keeps the object more than 7 AU from Neptune over a 14 000-year period.
