Previously, it was shown that the planets will separate from the Sun at future times. The separation times are determined by the rate of solar mass loss by radiation and solar wind. In continuation of the previous work, the final step of planetary separation, the mechanism of the opening of the planetary orbits, will be discussed. Changes of planetary orbital ellipticity with time are modeled based on current observations. The correlation between solar - planetary Focal Distance and planetary orbits reveals an abrupt increase between the orbits of Uranus and Neptune. The correlation between focal distance and orbit for the closer planets (Mercury to Uranus) increases twentyfold (20.2x) for the farther planets (Neptune to CR105). Comparison with properties of ellipses reveals that this transition must relate to changes in solar - planetary physical interactions. The magnitude of Eccentricity also revealed an increase between Uranus and Neptune. After a steep increase of eccentricity between Neptune and Pluto, the correlation approaches linearity between Eris and CR105. Extrapolation of the eccentricity correlation to 1.0 predicts an opening from elliptic to Hyperbolic orbits and thus of planetary separation at about 300AU (4.6E+10 Km). This limit presents the outer limit of the solar system. This limit is farther than that predicted for the heliopause at about 100AU (1.5E+10 Km). The history of the ellipticity of individual planets can be derived from the observed correlation of ellipticity with orbits, and the models of the orbital changes with time. This information may be included in models of the origin of the solar system.
