The mass of the compact object in the eclipsing binary SS 433 system is estimated. It is assumed that the radial velocities measured relative to the narrow emission components of the stationary H-alpha, H-beta emission lines represent gas streaming from the normal O-B component of SS 433 toward the accretion disk. The mass is estimated to be 0.3-5.0 solar masses, and results of photometry and polarimetry indicate that the accretion structure has a radius of approximately 0.5 a.
