Abstract
Here I present a new attempt to determine the mass of (4) Vesta, based on its close approaches with relatively well observed minor planets: (3057) Malaren, (5205) 1988CU7, (8331) Dawkins and (21225) 1995GQ1. The obtained values for the mass of (4) Vesta are comparable with earlier determined ones.


Key words: celestial mechanics -- astrometry
