Abstract
Scientific visualization is considered as prognostic method to treat the computer experiment results and to simulate the long-term existence of small celestial objects. The short-period IP/Halley comet with the stated existence period from 1404BC to 1986 AD and the rotation period of 76 years is chosen as an object of interest. The computer algorithm is based on a Monte-Carlo technique which in case of small body of input data gives valuable output information. Visualization of this information (graphs, plane and spatial images) allows the obtained results to be presented in a form more suitable for subsequent analysis. The analyses visual images allow one to know more about the cometary nucleus structure, disintegration rates and the expected mass replenishment of Orionids and ŋ-Aquarids. As a result, their activity may rise and in two comet rotations be dangerous for life activity on the Earth. The obtained results demonstrate the effectiveness of visualization for the purposes of celestial mechanics. Besides the advanced space exploration and a great number of the Earth-launched satellites enhance our interest just to the visual results which allow one to estimate the situation in space during launching and safe flights.
