Glossary term: Exoplanète
Description: Une exoplanète, ou planète extrasolaire, est une planète située en dehors du système solaire. Leur existence a été théorisée dès le XVIe siècle et la recherche observationnelle a commencé au XIXe siècle pour les trouver. Les premières exoplanètes confirmées ont été découvertes dans les années 1990. Parmi celles-ci, la première exoplanète confirmée en orbite autour d'une étoile de la séquence principale est l'exoplanète Dimidium, découverte indirectement à l'Observatoire de Haute-Provence. Cette exoplanète est en orbite autour de l'étoile 51 Pegasi, une sous-géante jaune, et a été découverte en 1995. Depuis, des milliers d'exoplanètes ont été identifiées.
