The results of dynamic modelling of the dust tail formation of comet C/2012 K5 (LINEAR) are presented. A Monte Carlo model developed by Korsun was used to fit the observed tail. The adequacy of the model was defined by the match of the observed and modelled isophotes. As a result of successful simulation we obtained the following physical parameters of comet dust particles that formed the tail: the range of radii (0.7—100 μm), the power index of the radius distribution law (–2.4), velocity range (6—135 m/s), the maximum age of the dust particles (88 days).
