Ganymede (Otherwise known as Jupiter III) is a moon of Jupiter and is the largest moon of Jupiter and is also the largest moon known in The Solar System. Ganymede was discovered in 7th January 1610 by Galileo Galilei . Ganymede is also the only moon in the Solar System to have a substantial magnetosphere .


Ganymede is the leader of moons . He prefers to think he's one of the greatest moons but isn't very cocky about it . Ganymede has been interested in Kepler-1625b I since he is the largest moon known in the Milky Way Galaxy which he isn't jealous about but he feels downgraded .
