119 free The Expanse trivia questions with answers — entertainment quiz, new questions added Aug 2026.
This The Expanse trivia quiz covers all six seasons of the Syfy and Amazon Prime Video series, from Julie Mao breaking out of a locker in "Dulcinea" to the Free Navy's last transit in "Babylon's Ashes". The easy questions are ones any viewer can handle: who plays Holden, Naomi, Amos and Alex, what the Rocinante was called before, which network cancelled the show and who saved it, and what the Belters call their language. The harder end is for people who can pronounce "Beltalowda" properly. It asks about the Canterbury and the Donnager, Ceres and Eros, the Nauvoo, Miller and Julie, Bobbie on Ganymede, the hybrids, Venus, the Ring and the Investigator, Ilus and Murtry, the Sojourner trial, the stealth asteroids, the Chetzemoka, Alex's death, Laconia's strange dogs, and how the Free Navy ends. There are also questions on the novels by James S. A. Corey, on Daniel Abraham and Ty Franck, the Hugo Awards, Belter Creole's creator, the Screaming Firehawks who saved the show, and the cast's other work from House of Sand and Fog to The Punisher. Every answer was checked against the encyclopaedia entries for the series, its episode list, the novels and the cast before publishing, and the supporting sentence is stored with each question.
