NEO Radar: A Browser-Based Engine Tracking 41,000 Real Asteroids

Neo Radar: A browser-based orbital mechanics engine with 41k real asteroids

I built NEO Radar to simulate real orbital mechanics for 41,859 Near-Earth Objects directly in your browser. Unlike simplified models, this engine uses full N-body dynamics and JPL Horizons data to calculate trajectories with mission-planner accuracy. You can toggle gravity from outer planets like Jupiter and Saturn to see how they perturb asteroid paths, revealing the true uncertainty cones that simplified two-body simulations miss.
