INPOP21a planetary ephemerides
Abstract
The major points of improvement of INPOP21a relative to INPOP19a are i) the addition of 2 years of Mars Express data and 1 year of Juno normal points, ii) the use of new Uranus ground-based optical observations reduced with the Gaia DR3, iii) the modification of the dynamical modeling for the Kuiper belt object perturbations, and iv) the first determination of the Sun oblateness including the Lense-Thirring effect.
