mySolar - Build your Planets

mySolar - Build your Planets is a creative space sandbox that lets you design and simulate your own solar systems. Build planets and other celestial bodies, set their size and orbit, and watch realistic gravity drive their motion in real time. Learn core space concepts through hands-on experimentation, from orbital mechanics and collisions to stability and habitability, making it ideal for curious learners and classrooms alike. With intuitive drag-and-drop controls, physics-based outcomes, and guided challenges, mySolar turns complex science into playful discovery. Create, test, and refine your designs to see how small changes shape the entire system.
