Orbit from osculating elements
243 Ida is placed by solving a Keplerian orbit at the simulation time (a = 2.9 AU, e = 0.0455, i = 1.1°, period 1,770 d).
Main-belt asteroid found to have its own moon, Dactyl (Galileo, 1993).
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.
243 Ida is placed by solving a Keplerian orbit at the simulation time (a = 2.9 AU, e = 0.0455, i = 1.1°, period 1,770 d).
243 Ida is identified from the cited source record.
243 Ida: mean radius 16 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.
