Glossary term: Titan
Description: Titan est la plus grande lune de Saturne. Elle est plus grande que la Lune de la Terre et que Mercure, et se classe au deuxième rang des lunes du système solaire. C'est le seul corps autre que la Terre dont on sait qu'il possède des océans, des mers et des rivières liquides à sa surface. Ceux-ci sont toutefois constitués de substances chimiques appelées hydrocarbures. On pense que Titan possède un noyau rocheux et une croûte de glace composée d'eau. On pense que l'eau liquide sous la croûte de glace pourrait abriter de la vie. Titan possède une atmosphère épaisse, composée principalement d'azote, qui lui donne un aspect très lisse sur les images.
