provenance RAW — read directly from a source catalogue, unaltered
Open Ariel in the live scene → The scene composes a position for any date and is where a figure becomes a picture. It downloads the whole catalogue first: measured against the built product, an object outside the core resolves after about 16 s over a local network and about 147 s over a 4 Mbit link, having transferred roughly 70 MB. If you cannot wait that long, this page is the answer.
The registry keeps every source's value rather than choosing one and discarding the rest. If you quote a figure below, quoting it alone would hide a real disagreement between catalogues.
orbital.e: the registry shows one value and keeps 1 other — 0.001 (JPL SSD sats/elem)tagged.mass: the registry shows one value and keeps 1 other — 1.34×10^21 (GCAT worlds)| Quantity | Value | Uncertainty | Source |
|---|---|---|---|
| Radius | 578900 m (578.9 km) | no published uncertainty in this registry | Solar system (curated) ✓ confirmed by 2 further sources: JPL SSD phys_par, GCAT worlds |
| Mass | 1.251×10^21 kg | no published uncertainty in this registry | Solar system (curated) ⚖ 1 source disagree — 1.34×10^21 kg (GCAT worlds) |
Each row carries its own uncertainty and its own source. Where a row says no uncertainty is published, that is what the catalogue says — it is not a claim that the value is exact.
These are the sourced elements. This page does not print a position: a position is a function of time, and a single one dated to the bake would be stale the moment it was read. The registry composes a position for any date, past or future, from these elements — open the scene below and set the clock.
