Note also that Pluto is still the largest trans-neptunian object, at a
couple thousand miles diameter, and crosses Neptune's orbit, while most
of the other objects remain outside its orbit. There are a few objects a
couple hundred miles across that are in similar resonant orbits, but
most remain outside, and are not influenced much at all (and don't
influence Neptune) due to the distance...
