Bespin's atmosphere was mostly rethen
Rethen was the predominant gas in the atmosphere of the gas giant Bespin. It had a faintly sweet smell, comparable to that of pancakes drenched with syrup, and was only mildly toxic to human lungs.[1]
Behind the scenes
Rethen first appeared in the 1980 original trilogy film, Star Wars: Episode V The Empire Strikes Back.[2] However, it was first identified as such in Adam Gidwitz's The Empire Strikes Back: So You Want to Be a Jedi?, a retelling of the movie that was published in 2015.[1]
