The oort cloud

The Oort cloud is a cloud of predominantly icy planetesimalsproposed to surround the Sun at distances ranging from 2,000 to 200,000 AU. It is divided into two regions: a disc-shaped inner Oort cloud and a spherical outer Oort cloud. Both regions lie beyond the heliosphere and in interstellar space. The Kuiper belt and the scattered disc, the other two reservoirs of trans-Neptunian objects, are less than one thousandth as far from the Sun as the Oort cloud.

this region is under control of the united hothi league, and it is known that their vessels patrol this area heavily based on observations by the hubble space telescope
