Jupiter is the fifth planet in the solar system and is classified as a gas giant. It is the largest planet that orbits the Sun. Due to its size, the planet possesses a powerful gravity field, and its gaseous atmosphere is in constant turmoil. Gamilas used the Floating Continent, a large landmass found floating in the planet's upper atmosphere, for a military base. Jupiter's strong gravity trapped the battleship Yamato in 2199, which led to the crew's discovery and subsequent destruction of the Floating Continent ("Escape the Floating Continent! Crisis Calls the Wave-Motion Gun!").
