One record per aspect. The origin says what kind of thing each value is; the source says where it came from; the limit says what it cannot tell you.
Trajectory from Horizons state vectors
Voyager 2's position is interpolated between 2,475 heliocentric state-vector samples from JPL Horizons that run through 2049-12-17. Past the last sample the marker holds its final position.
Epoch1977-08-21 to 2049-12-17
MethodJ2000 equatorial, Sun-centred position samples loaded from a versioned Blob snapshot. Historical encounter samples are preserved; active mission windows are refreshed daily by Trigger.dev in UTC. The app interpolates linearly between adjacent samples.
UncertaintyAccuracy depends on the mission ephemeris and prediction horizon. Linear interpolation adds error that grows with sample spacing (hours in the current window, finer around historical flybys). No trajectory covariance is stored.
LimitPosition only. Spacecraft attitude (which way it points) is not modelled, and no covariance is stored.
Physical data
Undocumented
Bulk properties
Voyager 2: mass 7.219 × 10^2 kg. These values are bundled with the object record and drive the rendered size.
SourceBundled object record
LimitThe object catalog does not record where these values came from; treat them as unverified until the record is completed.
Close-up hull model
The close-up shows a published 3D model scaled to 13 m deployed magnetometer-boom extent. NASA Visualization Technology Applications and Development (VTAD).
MethodSpace Time normalises the source model to the published deployed dimension.
LimitSource-asset presentation pose; time-dependent flight attitude is not modeled.
Description and facts
The short description and the fact list are written by the Space Time authors for orientation. They are not quoted from a catalog field and carry no citation of their own.

Trajectory coverage: 1977-08-21 to 2049-12-17 (2,475 samples). Outside that window the marker holds its last known position.
