Mars Quiz

Mars Quiz is a light and engaging challenge based on mars planet trivia and real facts. In the 1800s, Italian astronomer Giovanni Schiaparelli observed dark lines on Mars and called them “canali.” Although he meant “channels,” it was wrongly translated as “canals,” leading many to believe they were built by intelligent Martians. This mistake sparked a wave of theories and science fiction stories about life on Mars. While we know more now, the mystery never fully faded. These mars multiple choice questions bring you closer to the planet by mixing science with stories that once fascinated the world all without being too complicated.
