After all, its inner edge is roughly 2,000 AU away - 300 billion kilometers from the Sun. The Sun's gravitational influence in that region is rather weak, so the Cloud can be easily subjected to other effects. Galactic Tides WebApproximately 25% of the 82 new class I Oort cloud comets have an anomalous distribution of orbital elements that can best be understood if there exists a bound perturber in the outer Oort cloud. Statistically significant correlated anomalies include aphelia directions, energies, perihelion distances, and signatures of the angular momentum change due to …

Others arc on trajectories that swing them around periodically—in the case of Halley, once every 76 years. Some were flung far out, to where they now lurk in the Oort cloud.
