• Construction of physical model of an asteroid is based on the observations by different methods and the obtaining of lightcures in the visual and near-IR bands, variations of linear and circular polarization and spectra in the 0.38 - 1.05 m m wavelengh range vs asteroid rotational phase. On the basis of the obtained and published data we create a physical model of selected asteroid including pole position and shape, map of surface features, optital properties and mineralogy of surface.
• Construction of the photometrical model of an asteroid which includes the arbitrary shapes of a body, a law of brightness distribution over asteroid disk and phase function.
