Space Time
Lucy’s first asteroid encounter, accompanied by the contact-binary moon Selam.
Also known as 152830, 152830 Dinkinesh, 1999 VD57.
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.
Dinkinesh is placed by solving a Keplerian orbit around sun at the simulation time (a = 2.2 AU, e = 0.1126817135846694, i = 2.1°, period 1,185.2 d).
Dinkinesh is presented using measured bulk dimensions; illustrative ridge and rotational pole data.
Dinkinesh: mean radius 0.4 km. These values are bundled with the object record and drive the rendered size.
The surface is a procedural shape unless a source record above says otherwise. It is not a measured shape model.
Measured diameter and spin period; an illustrative equatorial ridge. Surface texture, pole and unseen geology are not measured here.
Measured bulk dimensions constrain the navigable bodies. Their ridge, neck, spin pole and unseen terrain remain approximate; these are not mission terrain meshes.
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.
