[Importance des programmes d'observation des objets géocroiseurs]
L'étude des objets géocroiseurs (NEO ou Near Earth Objects) s'est considérablement développée sous de multiples aspects sous l'impulsion notable des recherches concernant les risques de collision avec la Terre. Les observations jouent dans ce contexte un rôle primordial. Cet article s'attache à souligner leur importance pour accroître notre connaissance de ces objets et la nécessité d'en organiser des coordinations spécifiques. Il développe les objectifs de ces observations, explicite des méthodes pour réaliser la détection de nouveaux objets, discute de leur suivi et de l'archivage des données, donne des informations sur leur utilisation pour améliorer la connaissance de leurs orbites et sur l'influence du choix des théories planétaires prises en compte dans le modèle.
The study of NEOs (Near Earth Objects) has considerably been developed in several ways under the huge impulse of the research on the risks of an hazardous collision with the Earth. In this context observations play a very important role. This article attempts to underline their importance in improving our knowledge of these objects and the necessity of organizing dedicated programs. It develops the objectives of these observations, describes methods to perform the detection of new objects, discusses their follow-up and the necessity of finding using archives. It also gives information about the fit of the observations in order to improve the knowledge of the orbits of NEO and about the effect of the planetary theories taken into account in the model.
