  journal={The Astrophysical Journal},
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 showed no severe instability arising over this time interval. Subsequently, utilizing a bifurcation method described by Jacques Laskar, two numerical experiments were performed with the goal of determining dynamically allowed evolutions for the solar system in which the planetary orbits become… 
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
Dynamic stability of the Solar System: Statistically inconclusive results from ensemble integrations
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
Dynamical Evolution of Multi-Resonant Systems: the Case of GJ876
The GJ876 system was among the earliest multi-planetary detections outside of the Solar System, and has long been known to harbor a resonant pair of giant planets. Subsequent characterization of the
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.
Numerical Solutions for the Orbital Motion of the Solar System over the Past 100 Myr: Limits and New Results
I report results from accurate numerical integrations of Solar System orbits over the past 100Myr with the integrator package HNBody. The simulations used different integrator algorithms, step sizes,
Chaotic Disintegration of the Inner Solar System
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
Is the Solar System Stable
Since the formulation of the problem by Newton, and during three centuries, astronomers and mathematicians have sought to demonstrate the stability of the Solar System. As mentioned by Poincare,
Secular Effects of Tidal Damping in Compact Planetary Systems
We describe the long-term evolution of compact systems of terrestrial planets, using a set of simulations that match the statistical properties of the observed exoplanet distribution. The evolution
Existence of collisional trajectories of Mercury, Mars and Venus with the Earth
Numerical simulations of the evolution of the Solar System over 5 Gyr, including contributions from the Moon and general relativity find that one per cent of the solutions lead to a large increase in Mercury’s eccentricity—an increase large enough to allow collisions with Venus or the Sun.
Orbital stability of compact three-planet systems, I: Dependence of system lifetimes on initial orbital separations and longitudes
We explore the orbital dynamics of systems consisting of three planets, each as massive as the Earth, on coplanar, initially circular, orbits about a star of one solar mass. The initial semimajor


Long-term integrations and stability of planetary orbits in our Solar system
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
A numerical experiment on the chaotic behaviour of the Solar System
LAPLACE and Lagrange made an essential contribution to the study of the stability of the Solar System by proving analytically that, to first order in the masses, inclinations and eccentricities of
Chaotic diffusion in the Solar System
Abstract The discovery of the chaotic behavior of the planetary orbits in the Solar System [Laskar, J., 1989. Nature 338, 237–238; Laskar, J., 1990. Icarus 88, 266–291] was obtained using numerical
The origin of chaos in the outer solar system
The theory shows that the chaos among the jovian planets results from the overlap of the components of a mean motion resonance among Jupiter, Saturn, and Uranus, and provides rough estimates of the Lyapunov time and the dynamical lifetime of Uranus.
The chaotic motion of the solar system: A numerical estimate of the size of the chaotic zones
Abstract In a previous paper (J. Laskar, Nature 338, (237–238)), the chaotic nature of the Solar System excluding Pluto was established by the numerical computation of the maximum Lyapunov exponent
The Frozen Earth: Binary Scattering Events and the Fate of the Solar System
Abstract Planetary systems that encounter passing stars can experience severe orbital disruption, and the efficiency of this process is enhanced when the impinging systems are binary pairs rather
Solar system dynamics
The Solar System is a complex and fascinating dynamical system. This is the first textbook to describe comprehensively the dynamical features of the Solar System and to provide students with all the
Chaotic Evolution of the Solar System
This calculation confirms that the evolution of the solar system as a whole is chaotic, with a time scale of exponential divergence of about 4 million years, and indicates that the Jovian planet subsystem is chaotic.
