Saturn (2199)

Saturn is a ringed gas giant, the sixth planet in Earth's solar system.

Days after departing Earth in early 2199, the space battleship Yamato detects the distress signal of another Earth vessel originating from the vicinity of Saturn. Diverting to Saturn requires a significant change from Yamato's planned course and members of the senior staff initially resist investigating, until a serious engine failure compels them to visit one of Saturn's moons, Enceladus, for a rare mineral that would be vital to making repairs. The Great Garmillas Empire, maintaining a reconnaissance presence near Saturn, tracks Yamato's movements and launches an attack ("Gravestone on a Frozen Field").

Saturn becomes the site of a major battle between the United Nations Cosmo Navy fleet and the military of the Gatlantis Empire several years later. After hit and run attacks elsewhere in the solar system, Gatlantis commits a large portion of its forces to attacking the UNCF ships gathering above Saturn's rings. With the tide of battle turning toward Gatlantis, a subsequent wave of UNCN ships hiding below the rings fires through them into the unsuspecting enemy ranks, and rises through the ice particles of the rings to engage at close range. The Earth fleet presses the attack and nearly achieves victory until Gatlantis' "White Comet," the massive battle fortress at the heart of the empire, emerges from warp near the planet. In a show of power, the White Comet disintegrates Saturn and its rings ("Saturn's Offshore Battle - Gather the Wave Motion Fleet", "Yamato's Despair - Once More, the Devil's Alternative").

The planet is called "Zedan" in the Garmillas language ("Gravestone on a Frozen Field").
