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
253 Mathilde is placed by solving a Keplerian orbit at the simulation time (a = 2.7 AU, e = 0.264, i = 6.7°, period 1,570 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.
253 Mathilde source record
253 Mathilde is identified from the cited source record.
Bulk properties
253 Mathilde: mean radius 26.4 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.
