Satellite Reentry Traffic (2D)
Top-down orbital-decay lab: each satellite's altitude shrinks under atmospheric drag until it burns up, while a conjunction-radius check tracks how close decaying orbits pass to each other.
This 2D companion plots low-Earth-orbit satellites from directly above Earth and decays each one's orbital radius with an exponential-atmosphere drag model, da/dt = −k·ρ(h)·v, so altitude loss accelerates the lower and slower a satellite gets until it crosses the reentry line and burns up; a conjunction check flags any two orbits currently within the adjustable proximity radius, driving the live collision-risk readout, and an optional avoidance mode nudges flagged satellites apart the way real operators manage crowded orbital shells.
