Data provenance

Stable IDs keep selection and parent relationships consistent. See the body-by-body roadmap for future additions.

The table above is the 128-body core scene. The complete small-body atlas separately exposes 1,564,244 JPL catalog entries through bounded search and orbital previews, with explicit selected-body experiments.

The 115 Jovian moons use JPL mean orbital elements and the versioned satellite snapshot. Mass is derived from published GM / G. Missing physical values remain Unknown; 106 moons are modeled as massless test particles with nonphysical wire markers. Published estimates are labeled. These are representative orbital shapes and orientations, not dated ephemeris states.

Current constants are educational baseline values, not epoch state vectors. Jupiter through Neptune use JPL physical parameters and JPL approximate orbital elements. Saturn's visible ring extent and tilt follow NASA's Saturn facts, but the rings remain renderer-only. Satellite values use JPL Solar System Dynamics physical parameters; Vesta's pinned values are attributed to JPL SBDB solution 36, while the live SBDB query can change. Derived periapsis distances and vis-viva speeds remain in the source constants. The provenance policy records legacy retrieval-date and uncertainty gaps.
