Hi all:

Depending on albedo, there could easily be Earth-sized bodies beyond the
Kuiper Belt (do not remember the exact numbers off the top of my head but
could find out). As far as perturbations are concerned, we are likely to be
getting comets from the Oort cloud (that is how it was predicted) and these
could knocked out of the cloud by passing stars the cloud goes out to nearly
1/2 an AU, so there are stars that do get faily close to that distance.
