A geometrical model is suggested for the SS 433 stellar system consisting of a compact object and a star revolving around each other. The system includes a precessing accretion disk around the compact object and a hotspot on the disk surface. With these elements, most of the photometric characteristics of the system described in Leibowitz et al. (1984) can be accounted for, as well as a few other observations of this star. The parameters of the model adjusted by a least squares procedure yield a mass ratio in the system of 0.8 or higher. Combined with results of radial velocity measurements by Crampton and Hutchings (1981), the model parameters imply that the compact object is probably a black hole of 10-100 solar masses, the star is an early B, an O or a super-massive star. The average accretion rate in the system is larger than 0.00025 solar masses/yr. Two possible physical interpretations of the model are proposed and a few predictions are made for additional tests of the model against future observations.
