The planet Jupiter is visited for the filming of Spaceboy Zoom and His Dog Astro. Humans didn't need to use breathing apparatuses, and they were able to stand-up comfortably on the surface of the planet. Anti-gravity belts even work normally on the planet.
Uniblab mentions a card game called Jupiter Gin.
The solarium salt mines of Jupiter are mentioned, with the implication being it is undesirable to work there.
