1.2 Solar System object astrometry

Author(s): P. Tanga

This FPR contains updated astrometry and the orbits for Solar System objects that were published as part of Gaia DR3. The update consists of using the observations covered by the Gaia DR4 time baseline, processed with essentially the same pipeline as used for Gaia DR3. In addition the Solar System object orbits are also included as part of the FPR. We recall here that preliminary orbit solutions were provided in Gaia DR3 as auxiliary data. The FPR version represents a totally different determination of the orbits, fully integrated in the processing pipeline. It is intended to replace completely the previous solution.

No new epoch photometry or reflectance spectra are included in this FPR.

The data processing and properties for Solar System objects in this FPR are described in Gaia Collaboration, David, P., et al. (2023a).
