Kessler Syndrome: Orbital Debris Threshold Simulator

Set the initial density of an orbital debris shell and run it forward through simulated years. Below a critical density the population decays back to a stable low level; above it, collision-spawned fragments outpace natural decay and the shell runs away into a Kessler cascade. Compare two runs side by side on a live object-count chart.

Set the initial density of an orbital shell and run it forward through simulated years. Below a critical density, natural decay keeps the population roughly stable; above it, collision-spawned fragments raise the collision rate faster than decay can remove them, and the shell runs away into a self-sustaining debris cascade.

⚙ Under the hood

Set the initial density of an orbital debris shell and run it forward through simulated years. Below a critical density, natural decay keeps the object count roughly stable; above it, collision-spawned fragments raise the collision rate faster than decay can remove objects, and the shell runs away into a self-sustaining Kessler cascade. A live chart keeps the previous run visible as a ghost trace so you can compare stable vs runaway outcomes directly.
