Abstract
Masses of large asteroids are needed for improving modern planetary ephemerides. 239 minor planets with diameter bigger than 100 km have been selected for mass determination through close encounters with all numbered and unnumbered asteroids. To this aim, the orbits of 11000 numbered and 35000 unnumbered minor planets in the time interval 1985-2010 have been integ- rated. The inftuence of the epoch of Observations and the relation between the accuracy in the mass determination and data distribution are investigated.
