Bespin

Bespin was a gas giant in the Force Galaxy that was home to many wealthy mining colonies, such as the elaborate Cloud City, facilitated by Lando Calrissian. The legendary Duel on Bespin took place here, during which Darth Vader revealed to Luke Skywalker that he was his father. It was also here that Han Solo was frozen in carbonite by the Empire and handed over to Boba Fett.

Following this, Bespin largely faded from the Galaxy's agenda. Although it was visited several times by Kyle Katarn during his travels around the Galaxy. Bespin was not a largely populated planet due to its nature as a Gas Giant, however, it holds the honour of being the most heavily populated Gas Giant in the Galaxy.
