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
25143 Itokawa is placed by solving a Keplerian orbit at the simulation time (a = 1.3 AU, e = 0.28, i = 1.6°, period 557 d).
Epoch2025-11-21T00:00:00Z
MethodTwo-body propagation of the stored elements by the shared orbit service; no perturbations.
LimitA two-body orbit ignores planetary perturbations and non-gravitational forces; the dated JPL snapshot in the app's live catalog supersedes these bundled elements.
25143 Itokawa source record
25143 Itokawa is identified from the cited source record.
Bulk properties
25143 Itokawa: mean radius 0.2 km. These values are bundled with the object record and drive the rendered size.
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.
