Description
I discuss how the proposed instability of the giant planets that
sculpted the Kuiper Belt and Scattered Disc also formed the Oort comet
cloud. I show the results of numerical simulations of this problem and
discuss formation efficiency, number of comets in the cloud and the Oort
cloud to Scattered Disc population ratios. I compare these with
observations and give an updated estimate based on the fading of
Jupiter-family comets. These results indicate that the Oort cloud and
Scattered Disc formed simultaneously and that the observed population
ratio matches numerical simulations.
