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
C/1995 O1 (Hale-Bopp) is placed by solving a Keplerian orbit at the simulation time (a = 186 AU, e = 0.995, i = 89.4°, period 926,000 d).
SourceBundled orbital elements
EpochJD 2450538.5
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
C/1995 O1 (Hale-Bopp): mean radius 30 km. 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 nucleus, coma and tail are identification geometry. Tail direction follows the propagated orbit and the Sun direction; the local shape is representative.
SourceSpace Time rendering contract
LimitNot a resolved observation.
