Solar system
A 3D orbit viewer for the major planets. Use “Live snapshot (JPL)” to pull planet positions from NASA/JPL Horizons.

Visualization note: orbits are simplified. “Live snapshot” uses the NASA/JPL Horizons API and may show small coordinate-system differences depending on parameters.
Next upgrades
- Use JPL Horizons state vectors continuously to animate real ephemerides over time.
- Add moons, asteroids, and spacecraft ephemerides.
- Connect planets/objects into the knowledge graph with citations.
