We present the results of very long-term numerical integrations of planetary orbital motions over 10 9 -yr time-spans including all nine planets. A quick inspection of our numerical data shows that the planetary motion, atleast in our simple dynamical model, seems to be quite stable even over this very long time-span. A closer look at the lowest-frequency oscillations using a low-pass filter shows us the potentially diffusive character of terrestrial planetary motion, especially that of Mercury… 

On the Dynamical Stability of the Solar System

A long-term numerical integration of the classical Newtonian approximation to the planetary orbital motions of the full solar system (Sun + eight planets), spanning 20 Gyr, was performed. The results


Due to the chaotic nature of the solar system, the question of its dynamic long-term stability can only be answered in a statistical sense, for instance, based on numerical ensemble integrations of

The stability of the terrestrial planets with a more massive ‘Earth’

Although the long-term numerical integrations of planetary orbits indicate that our planetary system is dynamically stable at least ±4 Gyr, the dynamics of our Solar system includes both chaotic and


Due to the chaotic nature of the solar system, the question of its long-term stability can only be answered in a statistical sense, for instance, based on numerical ensemble integrations of nearby

Long-Term Stability and Dynamical Environment of the PSR 1257+12 Planetary System

We study the long-term dynamics of the PSR 1257+12 planetary system. Using the recently determined accurate initial condition by Konacki & Wolszczan, who derived the orbital inclinations and the


On timescales that greatly exceed an orbital period, typical planetary orbits evolve in a stochastic yet stable fashion. On even longer timescales, however, planetary orbits can spontaneously

The orbital evolution of the Sun–Jupiter–Saturn–Uranus–Neptune system on long time scales

The averaged semi-analytical motion theory of the four-planetary problem is constructed up to the third order in planetary masses and the sixth degree in the orbital eccentricities and inclinations.

Overlong simulations of the solar system dynamics with two alternating step-lengths

We compare the performance of four symplectic integration methods with leading order symplectic corrector in simulations of the Solar System. These simulations cover 10 Gyr. They are longer than the

A long-term numerical solution for the insolation quantities of the Earth

We present here a new solution for the astronomical computation of the insolation quantities on Earth spanning from -250 Myr to 250 Myr. This solution has been improved with respect to La93 (Laskar

Surfing on the edge: chaos versus near-integrability in the system of Jovian planets

We demonstrate that the system of Sun and Jovian planets, integrated for 200 Myr as an isolated five-body system using many sets of initial conditions all within the uncertainty bounds of their



The Stability of Multi-Planet Systems

A system of two small planets orbiting the Sun on low-eccentricity, low-inclination orbits is stable with respect to close encounters if the initial semi-major axis difference, Δ, measured in mutual

Dynamics of Systems of Two Close Planets

Abstract In connection with the study of newly formed protoplanetary embryos in the early Solar System, we study the dynamics of a pair of interacting planets orbiting a Sun. By examining the

Stability and Instability of the Terrestrial Protoplanet System and Their Possible Roles in the Final Stage of Planet Formation

Abstract Recent studies indicate that the formation of jovian giant planets (probably Jupiter and possibly Saturn) may have preceded the formation of terrestrial planets because of the rapidity of

A Three Million Year Integration of the Earth's Orbit

The equations of motion of the nine planets and the Earth's spin axis are integrated for 3.05 million years into the past. The equations include the dominant relativistic corrections and corrections

Large scale chaos and marginal stability in the solar system

Large scale chaos is present everywhere in the solar system. It plays a major role in the sculpting of the asteroid belt and in the diffusion of comets from the outer region of the solar system. All

The Stability of Protoplanet Systems

Abstract We investigated the stability of 10 protoplanet systems using three-dimensional N-body simulations. We found that the time scale of instability T depends strongly on the initial random

Long-Term Planetary Integration With Individual Time Steps

We describe an algorithm for long-term planetary orbit integrations, including the dominant post-Newtonian effects, that employs individual timesteps for each planet. The algorithm is symplectic and

Chaos in the solar system

We have accumulated thousands of orbits of test particles in the Solar System from the asteroid belt to beyond the orbit of Neptune. We find that the time for an orbit to make a close encounter with

Long-term behavior of the motion of Pluto over 5.5 billion years

The motion of Pluto is said to be chaotic in the sense that the maximum Lyapunov exponent is positive: the Lyapunov time (the inverse of the Lyapunov exponent) is about 20 million years. So far the
