Statistical Properties of Encounters among Asteroids: A New, General Purpose, Formalism

Icarus, 1998
Abstract The statistical properties of asteroid mutual encounters have been studied by several authors, with the main purpose of estimating collisional rates (and thus mean collisional lifetimes) and the distribution of encounter velocities. In this paper we present a new approach, conceptually not really different with respect to the classical ones,
