Numerical Evidence That the Motion of Pluto Is Chaotic

Numerical Evidence That the Motion of Pluto Is Chaotic

G J Sussman et al. Science.

Abstract

The Digital Orrery has been used to perform an integration of the motion of the outer planets for 845 million years. This integration indicates that the long-term motion of the planet Pluto is chaotic. Nearby trajectories diverge exponentially with an e-folding time of only about 20 million years.
