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).

Data source

https://ssd.jpl.nasa.gov/api/horizons.api and /horizons_lookup.api.

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.
