Kessler cascade model

Thousands of tracked fragments orbit at different altitudes and inclinations. When two objects pass close enough, a collision spawns new fragments — raising the risk of a runaway cascade.

Lower orbits (near Earth) move faster than higher ones, matching real Kepler dynamics. Raise density or lower avoidance to trigger a cascade — each collision can spawn new fragments, which raises the odds of the next one.
