🌌 Galactic Dark Matter Halo: 2D Orbit Map

Interactive 2D model of a galaxy embedded in a dark-matter halo: thousands of stars orbit in a combined NFW halo, disk and bulge potential while a satellite galaxy you launch is tidally stripped into a stream, with a live rotation-curve graph showing why the halo is needed.
