Use of differential equations in the form of Encke for the study of motion small solar system bodies
Zausaev D.A.
Abstract

The numerical integration of differential equations of motion of small bodies in the solar system is considered in the form of Encke . For short-period comets and asteroids Apollo and Aten, a comparison of the results of numerical integration of the equations of motion in standard form and shape of the Encke is conducted. In this article has shown that the equations of Enke is preferable to use for celestial bodies, with close rapprochement with perturbing planets, as well as the use of methods of numerical integration of the low order.
