Geometric Conditions for Quasi-Collisions in öpik’s Theory

  • Giovanni B. Valsecchi
Part of the Lecture Notes in Physics book series (LNP, volume 682)


The geometric setup of the recently proposed extension of öpik’s theory of planetary close encounters is modified in order to allow the treatment of encounters taking place far from the nodes of the small body orbit.
