About this tool
The AI Astronomy Quiz Generator
An astronomy quiz generator has to handle scale — distances in AU and light-years, times in millions and billions of years, temperatures from kelvin to millions of degrees. This astronomy quiz maker produces questions on the solar system, stars, galaxies, and cosmology with numbers that check out and answer keys grounded in current astronomy, not 1980s-era facts that have since been revised.
Solar system, stars, and galaxies
Specify the unit and the generator stays inside it. Solar system covers the planets, moons, asteroids, comets, and Kepler's laws. Stars handles the HR diagram, stellar evolution, spectra, and nuclear fusion. Galaxies pulls from galaxy types, the Milky Way's structure, and Hubble's law. Cosmology includes the Big Bang, expansion, and cosmic microwave background. No mixing galactic-scale physics into a solar system quiz by accident.
Planets, moons, orbits, and Kepler's laws
Lunar phases, eclipses, seasons, and tides
Stellar classification, HR diagram, and stellar evolution
Galaxies, black holes, Hubble's law, and cosmology
Elementary through introductory college
Elementary astronomy sticks to identification and recall: name the planets in order, match the phase of the moon to the diagram, explain why we have seasons. Middle and high school adds Kepler's laws, stellar life cycles, and the HR diagram. Introductory college astronomy pulls in parallax calculations, Wien's law, and redshift. The astronomy practice test tunes to the grade you specify.
Diagram and calculation questions
Generated questions describe HR diagrams, orbital diagrams, and lunar phase arrangements in enough detail that students can reason without an image. For quantitative items, the answer key shows the equation (Kepler's third law, for example), the substitution, and the final number with correct units. Pair the printed quiz with a star chart or orbital diagram when you want students to work from an actual image.
From space-week quiz to full unit test
Five-question bell ringer on today's lunar phase, 10-question solar system quiz, 20-question unit test on stellar evolution — same astronomy quiz generator. Teachers use it for space-week in elementary, for the astronomy unit inside physical science or earth science, and for standalone high school astronomy electives.

Loved by Educators
Hear from teachers who are saving time and providing better feedback.
“For Chadwick users, GradeWithAI has improved feedback efficiency and effectiveness, as it is grounded in existing platforms and is highly adaptable.”
“More impressive though is that it corrects student answers not simply using a pre-written answer, but by following the thought process they've pursued.”
“I've really enjoyed using the GradeWithAI program. It saves me a ton of time, especially when I have class sizes of 35 or 36 students times five.”
“GradeWithAI doesn't just grade. It gives the student reasoning as to why every point is awarded or not awarded. That is a very valuable thing for the students.”
“GradeWithAI [provides] students with timely individualized feedback on their homework assignments and formative assessments. This is a job that is virtually impossible for a teacher to do on a regular basis.”
“Students have also appreciated the consistency and immediacy of the feedback I can provide through GradeWithAI. This has enabled them to make necessary corrections and achieve their desired scores on any assignment.”
