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.
Orbit from osculating elements
162173 Ryugu is placed by solving a Keplerian orbit at the simulation time (a = 1.2 AU, e = 0.1903, i = 5.9°, period 473.9 d).
SourceBundled orbital elements
EpochJD 2451545
MethodTwo-body propagation of the stored elements by the shared orbit service; no perturbations.
LimitThese elements are bundled with the object record without a recorded retrieval; the dated JPL Small-Body Database snapshot in the app's live catalog is the documented source for the same body.
Physical data
Undocumented
Bulk properties
162173 Ryugu: mean radius 0.5 km; mass 4.500 × 10^11 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 appearance
The surface is a procedural shape unless a source record above says otherwise. It is not a measured shape model.
SourceSpace Time rendering contract
LimitNot a resolved observation.
