The purpose of this work is to estimate the mass of the main asteroid belt and those of the individual asteroids. To solve thistask we propose to use Tikhonov regularization which allows to use a priori information on the asteroids’ masses and theiruncertainties. Each a priori mass and its uncertainty were calculated based on the infrared diameter and density estimatesof a particular asteroid. As a result, we managed to obtain mass estimates consistent with those obtained earlier, and toextend the list of asteroids whose masses are individually determined in the EPM dynamical model.
