La masse d’Uranus est 14,6 fois plus grande que celle de la Terre, son rayon est de 24,800 km. (...) On a calculé la direction de l’axe de sa rotation et il s’est avéré que l’équateur d’Uranus fait avec le plan de son orbite un angle de 82 °, et que sa rotation est rétrograde. Uranus possède cinq satellites. 1, record 5, French, - Uranus
