80 Jupiter Trivia Questions with Answers
80 public questions with answers, drawn from the well. How many can you answer?
Jupiter trivia spans the Solar System’s largest planet, its moons, Trojan asteroids, exploration missions and powerful place in planetary science. The 80 questions include the spacecraft that first orbited Jupiter, the date Juno entered orbit, the planet with the Solar System’s shortest day and the astronomer who proposed names for the four Galilean moons.
The hub also explores Jupiter’s wider neighborhood and history of exploration: the L4 Trojan group, the largest generally recognized Jupiter trojan, the spacecraft that used Jupiter for a gravity assist toward a polar solar orbit and the Space Shuttle launch that sent Galileo on its journey. It suits astronomy students, science classrooms, space enthusiasts and pub-quiz teams.

Jupiter trivia — quick answers
What are good Jupiter trivia questions?
Good Jupiter trivia questions cover its size, rapid rotation, moons, rings, atmosphere, Trojan asteroids and exploration history. Useful examples ask about Io, Europa, Ganymede and Callisto, the first spacecraft to orbit Jupiter, Juno’s arrival date, the L4 trojan group and Galileo’s Space Shuttle launch.
How hard is Jupiter trivia?
Jupiter trivia includes easy astronomy facts, such as its status as the largest planet and its very short day, as well as challenging mission and orbital details. The 80-question set is appropriate for mixed-ability game nights, while the spacecraft, Trojan and historical naming questions will especially reward science enthusiasts.
Which spacecraft first orbited Jupiter?
NASA’s Galileo spacecraft became the first spacecraft to orbit Jupiter when it entered orbit on December 7, 1995. Galileo studied Jupiter’s atmosphere, magnetosphere and major moons for years, and it also released an atmospheric probe. Its observations provided important evidence about the complex environments around the Galilean satellites.
What are Jupiter’s four Galilean moons?
Jupiter’s four Galilean moons are Io, Europa, Ganymede and Callisto. Galileo Galilei observed them in 1610, demonstrating that not everything orbited Earth. They differ dramatically: Io is intensely volcanic, Europa has an ice-covered surface and subsurface ocean interest, Ganymede is the largest moon, and Callisto is heavily cratered.
When did Juno enter orbit around Jupiter?
NASA’s Juno spacecraft entered orbit around Jupiter on July 4, 2016, UTC. The mission was designed to investigate Jupiter’s composition, gravity field, magnetic field and deep atmosphere. Juno’s polar orbit allows it to study regions and structures that earlier spacecraft, which followed different paths, could not observe as completely.
