AbstractWe propose to the NSFA (the IAU Working Group on Numerical Standards for Fundamental Astronomy) the following representative values and realistic uncertainties for the masses of the three largest asteroids (Ceres, Pallas, Vesta), to be used as the current best estimates: $$\begin{array}{ll}M_{\rm Ceres}/M_\odot \,=\, 4.72(3)\cdot 10^{-10},\\ M_{\rm Pallas}/M_\odot \,=\, 1.03(3)\cdot 10^{-10},\\ M_{\rm Vesta}/M_\odot\, =\, 1.35(3)\cdot 10^{-10}.\end{array}$$Unlike the values previously…
