Numerical Calculation and Analytic Formulas of Yarkovsky Effect Parameter of Circumsolar Asteroids

Abstract

The paper deals with two problems. The main problem is the parameter calculation for the Yarkovsky effect using analytic formulas and their comparison with that obtained through its inclusion in the number of parameters to be detected. Unknown physical parameters of asteroids are varied to obtain the boundary values from analytic formulas. Numerical calculations imply that acceleration driven by the Yarkovsky effect, is inversely proportional to the degree of the heliocentric distance. It is shown that numerical calculations for objects with a well-defined orbit are in good agreement with analytic boundaries. The second problem concerns the numerical calculation of the best degree value for the distance to the Sun. It is demonstrated that the best results are obtained at the degree value of 2.
