The Grand Orrery
A staged 3D solar-system mechanics instrument from the latest downloaded Grand Orrery bundle, kept separate from the Spiral Grand Orrery for review.

The Grand Orrery
This is a second Orrery instrument, staged beside the Spiral Grand Orrery rather than replacing it. It focuses on a precision 3D mechanics view with date controls, planetary inspection, event tools, bookmarks and poster output.

Assumptions used
What this answer assumes
These boundaries keep the calculation honest and make clear when a specialist rule set is needed.
- The staged route is noindex until Billy approves the calculator route.
- Planetary and event outputs depend on the embedded astronomy engine bundle.
- Visual scale and camera settings are presentation controls, not physical size claims.
- Source and certification notes must travel with the instrument before canonical promotion.
Master’s Tip
How to use the result well
Master’s Tip: keep the selected date with any exported chart. An orrery image without its epoch is not an auditable calculation.
Printable record
What belongs in the saved calculation
Set an epoch, inspect a planet, then compare the orbit and event panels so the chart remains tied to the selected date.

Atomic summary
The Grand Orrery is a separate staged 3D mechanics instrument.
The Spiral Grand Orrery is the helical reference-frame argument. This Grand Orrery is the broader mechanics workstation: date, planet, constellation, eclipse, bookmark and poster controls in a single 3D tool.
the-grand-orrery (3).zip and staged as a standalone public tool.CalculationTime narrative
A high-precision 3D model for astronomical visualization and commemorative charts.
The Grand Orrery is an interactive 3D model of the solar system, designed for accurate astronomical visualization and aesthetic exploration. Powered by the astronomy-engine physics library, it calculates planetary positions, orbital paths and phase context for a selected epoch.
Users can navigate the celestial mechanics of our solar system, observe planetary alignments, track historical eclipse context and explore the scale relationships of the cosmos. The built-in printing engine can generate poster-style astronomical charts for specific dates, making the staged tool useful as both a scientific reference candidate and commemorative visual art.
Epoch exploration
Set a date, scrub time and inspect how the solar-system arrangement changes around that moment.
Astronomy engine basis
The imported build uses astronomy-engine calculations rather than a purely decorative static scene.
Poster output
The print engine turns a chosen date and view into a chart that can be reviewed as reference or keepsake.

Certification notes
Source, licence and limitation basis
This staged wrapper treats The Grand Orrery as an educational 3D mechanics and charting instrument. It should not be promoted as a permanent canonical reference until the event panels, output claims, source licences and mobile controls have been checked against the same standard as Southern Cross Clock.
Model limits
The page is for visualisation and learning. It does not replace professional ephemerides, observatory software, mission-planning tools or safety-critical eclipse guidance.
Licence basis
The imported build uses React and astronomy-engine style calculations. Astronomy Engine is MIT licensed; the downloaded bundle still needs a final asset/licence inventory before launch.
