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.
Two-body orbit from published elements
Hayabusa2 is placed by solving a Keplerian orbit around ryugu at the simulation time (a = 20 km, e = 0.2, period 7 d). Shown from 2018-06-27 until 2019-11-13.
SourceBundled orbital elements
Epoch2018-06-27T00:00:00Z
MethodTwo-body propagation of the stored elements by the shared orbit service; no perturbations.
LimitA two-body orbit ignores perturbations, and the object catalog does not record which element table these values were copied from.
Physical data
Undocumented
Bulk properties
Hayabusa2: mass 6.090 × 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.
