  We study the post-encounter evolution of fictitious small bodies belonging to
the so-called Line of Variations (LoV) in the framework of the analytic theory
of close encounters. We show the consequences of the encounter on the local
minimum of the distance between the orbit of the planet and that of the small
body, and get a global picture of the way in which the planetocentric velocity
vector is affected by the encounter. The analytical results are compared with
those of numerical integrations of the restricted 3-body problem.
