It is a well established myth that the solar system is stable. The argument is generally based on the fact that the rate of the radiative plus solar wind mass loss of the Sun has a relatively small value of 8.81E-05 (1/Byr = 1/Ma) (radiative: 6.63E-05 (1/By)). Experimental results, e.g., that the Earth is separating from the Sun (10m/100year)(1), put the concept of stability of solar planetary orbits into doubt. An understanding of the stability of the solar system is a critical step towards the understanding of the stability of galaxies and the Universe.(2,3) The stability of planetary orbits, which is the other factor determining the stability of the solar system, has until recently not been modeled.(4) A model is presented which shows that the planetary orbits are weakly bound relative to orbital separation, ranging from 0.6 percent for Mercury to 0.006 for Pluto, and 0.0011 percent for CR105, the furthest reported planetesimal. These values are in the order of solar mass/gravity loss, and as a consequence, the model predicts that the solar system is expanding since its formation. The present separation rate of Earth is calculated to 3.0 m/year. Eventually orbital separation of planets will occur, e.g., at 133.8, 1.30, and 0.23 Billion years for Mercury, Pluto, Cr105, respectively under current conditions. The model shows that Mars was previously closer to the Sun and exposed to higher radiation, and that the transition from water to ice on its surface occurred 3.6 Billion years ago.(4) Predictions of the model are reported for all planets and dwarf planets.
