15 space questions appear one at a time. Each has four answer options. Choose the correct one before moving on. Questions cover the order of planets from the Sun, which planet is largest or smallest, which has rings, what the Sun is made of, how long Earth takes to orbit the Sun, and more fascinating solar system facts.

You have three lives. Wrong answers cost a life and show the correct answer briefly. Correct answers earn a point. A progress bar shows how far through the 15 questions you are. A final score screen tells you your result.

What Kids Learn

Knowledge of our solar system sits at the intersection of science and human curiosity - it answers the fundamental question "where are we?" in the biggest possible sense. The specific facts in this quiz (planet order, relative sizes, the nature of the Sun) are standard curriculum content from ages 8 onwards and provide the conceptual scaffold for later topics in physics, chemistry, and astronomy.

Beyond the facts themselves, the quiz builds the habit of scientific curiosity - the interest in knowing how the universe works rather than just how to navigate daily life. Children who develop this curiosity at a young age are significantly more likely to engage positively with science in secondary school.

Tips for Parents

Download a free star-gazing app and spend an evening identifying planets together - many are visible to the naked eye and knowing you are looking at Mars or Saturn creates an emotional connection to the science. NASA's free website for kids has wonderful photographs and videos. If your child becomes deeply interested, the library will have books on astronomy at every level from picture books to detailed guides for young readers.
