Zond-8 PAO is catalogued in this registry as a component, held in the frame of Earth, from GCAT — artificial space objects.
Registry id GCAT_A01871 ·
source layer gcat ·
provenance PROCESSED — derived deterministically from source catalogues (unit, frame and epoch conversions, cross-source reconciliation) — no value invented
Exists from 1970-10-20 19:55:38 UTC (JD 2440880.33031) until 1970-10-27 00:00:00 UTC (JD 2440886.5).
Open Zond-8 PAO 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.
| Quantity | Value | Uncertainty | Source |
|---|---|---|---|
| Radius | 4.9 m | no published uncertainty in this registry | GCAT — artificial space objects |
| Mass | 2880 kg | no published uncertainty in this registry | GCAT — artificial space objects |
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.
This object's parent frame changes over its life. Each leg names the frame it is expressed in and the source arc it came from. A leg with no geometry is a declared gap — the registry holds no path across it and draws none.
