A space round for classrooms, clubs and family quiz nights. The questions move from easy wins, like the Red Planet, to facts that surprise most rooms, like a planet whose day is longer than its year. Every answer comes with a one-line explanation you can read out after each question.

How to run it

  1. After each question, read the explanation aloud. The facts are what students remember.
  2. After question 3, show a picture of the planets in order so younger players can follow the rest.
  3. Before question 9, ask the room to guess out loud first. The answer surprises most people.
