Star Shepherd
An early solar-system sandbox prototype about shaping planets from a fixed ring of dust using nudges, orbits and gravity.
- For
- Players interested in planetary formation and sandbox games
- Worth noticing
- The page says its momentum, collision-energy and gravity equations inform collision research, not the game's solver.
Field notes
The page distinguishes the prototype’s implemented systems from work still underway: hot young worlds form and cool, while atmosphere and water remain in development. Its impact model uses visible-surface contact, and asteroid or comet trajectories are presented as aimed rather than magnetically corrected; comet tails brighten on approach and fade afterward. The habitable-zone overlay marks a range for possible surface liquid water, explicitly not a guarantee of life.
