This project simulates how planets move in a solar system over time. Set the number of planets with the slider and press the flag. All planets are generated with a random mass, initial velocity and initial position. You can pause with the simulation with the pause button, switch between trajectory mode and vector mode with the button next to that, and drag and drop the planets and sun with the mouse. Also, if there is only one planet, you can edit its velocity and mass manually. Enjoy!
