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.

How to play:
Start a new system and select a central star for your sandbox.
Add celestial bodies, set their size and mass, and drag to position them with an initial direction.
Adjust time speed and simulation settings to observe orbits, encounters, and collisions.
Experiment with planet properties to see how atmosphere, temperature, and composition affect stability and habitability.
Complete guided lessons or challenges to learn key concepts and unlock advanced tools.
Save your systems to revisit, compare, and continue improving their design.
