An interactive, physically accurate simulation of our solar system built entirely with vanilla HTML5, CSS, and JavaScript — no frameworks, no libraries.
Planetary orbits are computed in real-time from Keplerian orbital elements. Spacecraft trajectories use piecewise Hermite interpolation between state vectors. All rendering is procedurally generated using Canvas 2D and WebGL.
Orbital elements and spacecraft state vectors sourced from the NASA/JPL Horizons System.
