The Moon is Earth's only natural satellite, and is the sixth largest natural satellite in the Solar System. The moon first appeared in GTA III, and has been in every GTA game since then. It is assumed that the Moon revolves around Earth, like in real life. However, the moon is never referred to as doing so in any game, and it shows as a static image in all games since GTA III, fading into view at dusk and disappearing in the same way in the morning. Without mods there is no way to get to the Moon without hacking the game, as it is just an image. The moon is a helpful tool to navigate, as it gives some light to dark rural areas such as Back O' Beyond in San Andreas. It should be noted the GTA IV version of the moon is not as detailed and bright as in past games.
