Example solar system quiz questions

Which planet is the largest in the solar system?Jupiter. It holds more than twice the mass of all the other planets combined, so it dominates the system's orbits.

Why does Earth have seasons?Its axis is tilted about 23.4 degrees, so each hemisphere receives more direct sunlight at different times of the year.

True or false: Mercury is the hottest planet in the solar system.False. Venus is hotter because its thick carbon dioxide atmosphere traps heat, even though Mercury is closer to the Sun.

Between which two planets is the main asteroid belt located?Mars and Jupiter. Most asteroids orbit the Sun in this band between the two planets.

Which dwarf planet was reclassified in 2006?Pluto. The International Astronomical Union reclassified it because it has not cleared other objects from its orbital neighborhood.

Explanations on every answer

Each question comes with a short explanation of why the correct answer is right, so missed questions become study moments.

Pick the question types

Select multiple-choice, true/false or open questions and how many you want.

Take the quiz online

Answer in the browser, review the explanations, and export the quiz if you have a paid plan.

Frequently asked questions

How many questions should a solar system quiz include?

Ten to fifteen questions covers the planets, moons and dwarf planets without overwhelming one session. Shorter quizzes work well for quick review before a test.

What makes a good multiple-choice question about the planets?

The wrong options should be plausible, such as two planets with similar sizes, and the question should test one fact. Avoid answers that give away the correct choice through wording.

Moodle XML export is part of the Pro plan at $14.99 per month. Students who sign up with a school email get 40 percent off.

Is there a free plan to try it?
