the decade of this century has visible a renewed curiosity within the dynamics and physics of the small our bodies of the sunlight process, Asteroids, Comets and Meteors. New observational evidences comparable to the invention of the Edgeworth-Kuiper belt, subtle numerical instruments comparable to the symplectic integrators, analytical instruments similar to semi-numerical perturbation algorithms and regularly a greater figuring out of the dynamics of Hamiltonian platforms, most of these components have converged to make attainable and important the research, over long time spans, of those "minor" items. additionally the general public, the media or even a few political assell}blies became conscious that those "minor" items of our planetary environnement may well develop into lethal guns. it appears they did have a task in Earth heritage and a job extra ominous than "predicting" defeat (or victory, why not?) to batches of credulous rulers. Remembering what could have occurred to the dinosaurs yet conserving all of the discretion essential to steer clear of growing irrational scares, it will probably no longer be unwise or inappropriate to enhance our wisdom of the physics and dynamics of those items and to check particularly their interactions with our planet.
