Launch rockets, explore planets, watch the Moon change shape, and come face to face with a black hole! The universe is enormous — and all of it is waiting for you.
Blast off into the cosmos — no spacesuit required!
If Earth were a marble (12 mm), here's how the rest of the solar system compares
Drag the planets into the correct order from the Sun — can you get all 8?
Pick up a planet from the tray and drop it into the numbered slot.
5 questions — how much do you know about space?
Drag the slider from Earth all the way to the edge of the observable Universe!
Planets, rockets, stars, and space exploration — for young explorers
Space for Kids simulations introduce the wonders of astronomy and space science to young learners through age-appropriate interactive models. Colourful planet explorers let children orbit the solar system, see relative planet sizes, observe ring systems, and learn fun facts about each world — all without any maths or reading required beyond simple labels and icons.
Rocket simulation toys let children adjust thrust and angle to get a little rocket to the Moon, building an intuitive sense of trajectory and gravity without needing equations. Star-formation and constellation visualisers let children connect the dots of real star patterns and learn their mythological stories. Every simulation features large, easy-to-click controls and instant satisfying feedback, making science engaging for primary-school children and enthusiastic beginners of all ages.
Each simulation in this category is built with accuracy and interactivity in mind. The underlying mathematical models are the same ones used in academic research and professional engineering — just made accessible through a web browser. Changing parameters in real time and observing the results is one of the most effective ways to build intuition for complex scientific and engineering concepts.
