On the dynamics of Pluto

We study analytically the movement of the solar system planets and Pluto governed by Newton’s law of gravitation. It is proved that Pluto’s orbit remains stable at least for the next 30 000 years, in sense that the semi-major axis varies in the range from 38 AU to 41 AU, eccentricity varies in the r...

Description
Summary:We study analytically the movement of the solar system planets and Pluto governed by Newton’s law of gravitation. It is proved that Pluto’s orbit remains stable at least for the next 30 000 years, in sense that the semi-major axis varies in the range from 38 AU to 41 AU, eccentricity varies in the range from 0.2 to 0.3 and inclination varies in the range from 16.1◦ to 17.7◦. These results correspond to the numerical integration conducted in [1] and [2]. We also prove that the minimum distance between Neptune and Pluto will be within 2 AU to 6 AU, which is significantly less than 16.73 AU estimated in [1] (see also [3]).
