Asteroid kicked into the Oort cloud

First 2 million years of orbital evolution of an asteroid, born
in a circular orbit in 4:5 mean-motion resonance with
Jupiter. Repeated interactions with the giant planets (colored
circles: blue, orange, green and red for Jupiter, Saturn, Uranus and
Neptune, respectively) launched it along the conveyor belt into the
Oort cloud until it reaches the Hill sphere at a semi-major axis about
14,000au with eccentricity of more than 0.995. The inset to the lower left gives
the first 0.1 Myr of evolution, and the inset to the top right gives
the first 0.3 Myr. Each frame is on a different scale.
