The issue with objects with very elliptical orbits, is that it doesn't take much perturbation to turn then hyperbolic, and out of the solar system they go.
Bear in mind that not only do the orbits of planets/asteroids/comets vary over long time periods, so do the nearest starts.
We are talking incredibly tiny perturbations here, but on a billion year time scale, it's enough to fling objects out.
Various models of the solar system show proto planets being ejected from the solar system.
