- I post this whole mess to sci.space and say "help" because it seems that
- one side in a.f.u. is arguing as follows: _all_ asteroids occur between
- the orbits of Mars and Jupiter. Therefore Neptune, Pluto, etc. could not
- possibly have captured asteroids because asteroids don't go out that far.
