Bespin
Bespin is the planet in The Empire Strikes Back over which Cloud City hovers suspended by an antigravity pod. Bespin is also a major source of tibanna gas, which is refined for production and transport in Cloud City.The Millenium Falcon, by Han Solo's admission, just barely made it there from the Anoat system without hyperdrive. Although not seen in the movie, the Star Wars expanded universe shows much of Bespin's surface as swampland in which the short, porcine Ugnaughts live.
Lando Calrissian, the previous owner of the Millenium Falcon, administered Cloud City and provided well-paying jobs for the Ugnaughts until the Galactic Empire took over.
