Planetary Formation Simulator

Welcome! This is an interactive physics sandbox where you can create and observe the formation of planetary systems.


How it Works:

  • Use the controls in the Settings menu to define the physical properties of your new star system.
  • The simulation models gravity, particle collisions, and gas drag to show how a disk of dust and gas can evolve into planets.
  • Enable N-Body Physics to make every particle attract every other particle, allowing for realistic clumping and moon formation.
  • Create chaotic Binary or Trinary star systems and see how they affect planet development.
