NASA JPL Horizons MCP — solar-system body ephemerides (planets, moons, asteroids, comets, spacecraft). Keyless.

Tools

  • lookup(query) — resolve an object name → SPK id
  • ephemeris(command, center?, start_time, stop_time, step_size?, table_type?) — generate ephemerides
  • observers(command, center?, start_time, stop_time, step_size?) — observer (apparent position) table
  • vectors(command, center?, start_time, stop_time, step_size?) — Cartesian state vectors

command accepts SPK id (e.g. "499" Mars), name "Mars", or designation. center defaults to "500@399" (geocentric).

Tools

  • lookup — Resolve an object name → SPK id.
  • ephemeris — Generate an ephemeris (default observer table).
  • observers — Convenience: ephemeris with table_type=OBSERVER.
  • vectors — Convenience: ephemeris with table_type=VECTORS.
