# JPL/IAU solar factual derivative

Numeric facts from pinned JPL SSD physical and astrodynamic tables, JPL Horizons API snapshots and IAU2015 B3 nominal conversion constants. Source URLs/hashes/model labels/query parameters and per-field units/references are preserved. No image, logo, scientific prose or endorsement is copied or claimed. Planetary system GM values remain explicitly system values. All eight planets and41 installed moons have source geometric position/velocity components and explicit DE441 planetary-system reference bridges at JD2451545 TDB in Ecliptic-J2000, AU and AU/day, with no light-time correction. The six planetary-system barycenter samples use DE441. Local component states are translated through these explicit bridges, then the one DE441 Sun state is subtracted. Mercury and Venus need no satellite-system bridge. Per-body solution identifiers remain; this source-derived composition is not one unified N-body solution or an observational accuracy bound. Velocities are source facts, not permission to extrapolate. Original eight-planet/Moon osculating elements remain separate quantities. No propagation, current-date position or absolute accuracy claim. Satellite membership is the pinned physical table, not every known Solar moon. Radius-based spherical illustrations are not measured non-spherical shapes or observed surface maps. The explicit Sol identity bridge retains distinct AT-HYG3.3/HYG4.4 IDs and source hashes; those catalogs are by David Nash / Astronomy Nexus under CC BY-SA4.0 (https://creativecommons.org/licenses/by-sa/4.0/); retain that attribution for the bridge. No held Science NASA pack, private data or credentials are used.
