Ceres

Largest object in the asteroid belt. First asteroid discovered (1801).

Kepler elements Orbit basis, the same label the app shows on the selection card.

Every aspect, with its origin

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 Computed

Orbit from osculating elements

Ceres is placed by solving a Keplerian orbit at the simulation time (a = 2.8 AU, e = 0.0758, i = 10.6°, period 4.6 yr).

SourceBundled orbital elements
Epoch2000-01-01T12:00:00Z
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

Ceres: mean radius 473 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.
Appearance Reconstructed

Dawn grayscale mosaic

A reduced-resolution Dawn mosaic. Photographic shadows are baked in; this is not a live relief map or visible-light color image.

MethodThis describes the displayed appearance only; it does not certify catalog dimensions, orbital elements or unobserved geology.
Description Undocumented

Description and facts

The short description and the fact list are written by the Space Time authors for orientation. They are not quoted from a catalog field and carry no citation of their own.
