\noindent Abstract:

A purely numerical method for determination of asteroid masses is presented.
For the derivation of the mass use is made of asteroid close encounters, in
particular those very close. 

The procedure of the mass determination is based on finding a perturbed
orbit only by means of the observations collected after close encounter 
or only by those collected before the encounter, and of subseqent 
fitting of the observations on the other side of the close encounter 
by setting the trial values for the mass of a perturbing body and linking 
the pre- and post-encounter orbits. The resulting mass is obtained as one 
which gives the minimum O-C residuals in the RMS sense.
