🪐 Planet Formation in a Protoplanetary Disk, 2D

Interactive top-down N-body model of planets growing from a disk of planetesimals around a young star: mutual gravity, gas drag, collisions that merge bodies, a frost line where ice adds solid mass, and runaway gas accretion onto massive cores, with live mass-versus-orbit and growth plots.
