Viking is catalogued in this registry as a payload, held in the frame of Earth, from GCAT — artificial space objects.
Registry id GCAT_S16614 ·
source layer gcat ·
provenance PROCESSED — derived deterministically from source catalogues (unit, frame and epoch conversions, cross-source reconciliation) — no value invented
Exists from 1986-02-22 01:44:35 UTC (JD 2446483.57263) — no end date is recorded.
Open Viking 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 | 40 m | no published uncertainty in this registry | GCAT — artificial space objects |
| Mass | 260 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.
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.

EARTH at epoch
1986-04-24 00:00:00 UTC (JD 2446544.5). Gravitational parameter of the primary:
3.9861389×10^14 m³/s². Semi-major axis in astronomical units uses the
IAU 2012 definition (1 au = 1.495978707×10^11 m exactly).
