A Discussion of the Solution for the Motion of Pluto
Abstract
In a previous paper, a semianalytical solution for the longterm motion of Pluto was presented. The present paper contains: (1) a comparison of the present solution with the solution by Williams and Benson; (2) a discussion of the effect of the near resonance between Pluto and Uranus; and, (3) a calculation of the librational period of the eccentricity, inclination and perihelion. The semianalytical solution is shown to agree very closely with the longterm solution for Pluto obtained by Williams and Benson using numerical integration of the averaged equations of motion. A small difference between the two solutions is attributed to neglecting the eccentricity and inclination of Neptune in the semianalytical solution.
