Short: Animate up to 6 planetary masses. V1.50 Author: Richard Frost Version: 1.50 Architecture: m68k-amigaos Source: Fish collection A program to animate up to 6 planetary masses, all of which exert a mutual gravitational force on each other. The planetary masses can be placed anywhere on the screen, and their mass and initial velocity can be determined by the user. The program then steps the animation through time, plotting and displaying the new position in the trajectory of each mass.
