Asteroid masses obtained with INPOP planetary ephemerides
View through CrossRef
<p>We present here masses of 103 asteroids deduced from their perturbations on the<br />orbits of the inner planets, in particular Mars and the Earth. These determinations and the<br />INPOP19a planetary ephemerides are improved by the recent Mars orbiter navigation data<br />and the updated orbit of Jupiter based on the Juno mission data. More realistic mass estimates<br />are computed by a new method based on random Monte-Carlo sampling that uses up-to-date<br />knowledge of asteroid bulk densities. We provide masses with uncertainties better than 33%<br />for 103 asteroids. Deduced bulk densities are consistent with those observed within the main<br />spectroscopic complexes.</p>
