We model the polarization in the system HD 189733 resulting from the planetary transit. This system has a short-period (2.2d) Jupiter-like planet with the radii ratio Rp/R* = 0.148, orbiting at the distance of 0.031 AU around the star.

We calculated the polarization of the system HD189733 to be 0.022% at the limb, which is consistent with the recent observational data. We suggest the shapes of the polarization parameters curves to be used for deriving the planet orbit inclination at the near limb transits as an alternative to standard transit method.
