Orbit from osculating elements
4179 Toutatis is placed by solving a Keplerian orbit at the simulation time (a = 2.5 AU, e = 0.625, i = 0.4°, period 1,480 d).
Famous tumbling near-Earth asteroid, mapped by radar and Chang'e 2.
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.
4179 Toutatis is placed by solving a Keplerian orbit at the simulation time (a = 2.5 AU, e = 0.625, i = 0.4°, period 1,480 d).
4179 Toutatis is identified from the cited source record.
4179 Toutatis: mean radius 2.7 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.
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.
