This article is about the moon of Jupiter. For the city, see Ganymede (city).
Ganymede is a natural satellite governed by the Unified Earth Government and is the largest moon of Jupiter in the Sol system, being the only moon in the Sol System that is larger than the planet Mercury. It was partially terraformed though it supposedly retains a harsh climate. Ganymede is home to a significant human population.
The country Aigburth is located on Ganymede, as well as the Low/Zero Gravity Testing Facility, the developer of the EVA Armor. Subsequently, the EVA Armor was created and tested at Ganymede at Lister, Aigburth.
