On the Chandler Period of Venus

The Chandler wobble of Venus has been analyzed on the basis of the Earth-like models of the planet. The method for calculating the Chandler wobble period of Venus was tested on the example of the Earth. To take into account the inelasticity of the interior of a planet, the Andrade rheology was used; and the values of the rheologic model parameters, which can explain the observed period of the Chandler wobble of the Earth, were determined. Projections on the Chandler wobble period of Venus were obtained. For the most plausible models of the internal structure of Venus, in which the core radius is assumed to be within an interval of 3288 ± 167 km, the Chandler wobble period is 30–48 thousand years. A large error in the results is mainly caused by a wide range of probable values for the constant of precession of Venus.
