Cométographie est le fruit de dix années de recherches menées par Alexandre Guy Pingré, astronome et géographe français. Le livre examine l'histoire complète des comètes, de leur visibilité dans l'Antiquité à l'apparition de la comète de Halley. Pingré utilise une approche théorique et mathématique pour expliquer les mouvements cométaires et fournit également des observations détaillées pour chaque comète connue.
