Plots ~1,300 short-period comets in 3D using real Keplerian orbital elements pulled live from NASA JPL's Small-Body Database. Planet-to-planet sizes are real ratios; comet positions, eccentricities, and inclinations are mathematically accurate.
Some scales are stylized so everything fits on screen. Orbital distances are scaled uniformly (true scale would put Neptune ~12,000 units away). The Sun is rendered smaller than reality — at true 109× Earth it would engulf Mercury's orbit. Moon orbital distances are non-linearly compressed to sit beside their parent planets.
Each comet's color predicts its dominant gas emission based on perihelion distance — sodium tails near the sun, C₂ Swan-band green further out, blue CO⁺ ion tails in the cold outer system.
