Editing Oort cloud

The Sol system is home to a large Oort cloud, located approximately 0.79 light-years away from the star. There are numerous [[asteroid]]s, comets, and small planetoids located in the cloud.<ref name="HI1">''[[Halo: Initiation]]'', Issue #1</ref> The Oort cloud was used by the [[Office of Naval Intelligence]] for covert operations and constructions. The {{UNSCShip|Infinity}} was constructed within the Oort cloud,<ref>''[[Halo: Glasslands]]'', pages 421-422</ref> with construction beginning circa [[2544]].<ref name="Mythos132">''Halo Mythos'', pages 132-133</ref> Only high-ranking officers were informed of ''Infinity''<nowiki>'</nowiki>s existence. Construction workers remained stationed in the Oort cloud for years to ensure project secrecy.<ref>''Halo: Glasslands'', page 390</ref> Despite these precautions, in [[2553|January 2553]], the [[New Colonial Alliance]] discovered ''Infinity''<nowiki>'</nowiki>s location.{{Ref/Reuse|HI1}} The rebels, led by [[Ilsa Zane]], reached the Oort cloud with a [[D82-EST Darter|Darter dropship]] and infiltrated the ship disguised as construction workers.<ref>''Halo: Initiation'', Issue #2</ref> Eventually the rebels were eliminated and Zane was knocked into space. A [[prowler]] discovered her somewhere in the Oort cloud and took her aboard.<ref>''Halo: Initiation'', Issue #3</ref> ''Infinity'' first left the Oort cloud in [[2553|March 2553]], after a number of further upgrades to the ship from the [[Huragok]], to aid [[Arbiter]] [[Thel 'Vadam]] at [[Sanghelios]].<ref>''[[Halo: The Thursday War]]'', page 235</ref>

The Epsilon Eridani system was the location of a massive Oort cloud. Located on the very outer edges of the system, the cloud largely consisted of ice. This Oort cloud was noted as being too large to search in even a hundred years.<ref name="fs232">''[[Halo: First Strike]]'', page 232</ref> Within the Oort cloud, ONI discovered a planetoid with a [[Forerunner]] installation—designated "[[Site 17]]"—beneath its surface. Establishing [[Teller Station]] above the planetoid, ONI scientists spent years attempting to enter the Forerunner site. In the [[2552|summer of 2552]], with the beginning of the [[Fall of Reach]], the facility's defences prepared to abandon the station to combat the invading [[Covenant]] after one final attempt at entering the submerged installation. However, the effort led to the activation of Forerunner systems within the site, exposing the site's location to the Covenant [[Fleet of Valiant Prudence]].<ref>''[[Halo: Fleet Battles]]'', Scenario Three: Evacuate</ref> The scientists managed to recover an object from within Site 17 and prepared to leave the Oort cloud. While [[Supreme Commander]] [[Rho 'Barutamee]] ordered for parts of his fleet to recover the object and destroy the human researchers, Vice Admiral [[Michael Stanforth]] attempted to lure the Covenant forces into a trap at [[Reach]].<ref>''Halo: Fleet Battles'', Scenario Four: Run</ref> Following the [[Raid on Reach]], the [[human]]-captured ''[[Ascendant Justice]]'' exited [[slipspace]] in the Oort cloud to hide from the Covenant and to plot their next moves. [[Cortana]] had chosen to enter the system at the Oort cloud because she knew the Covenant would not be able to find them inside of it.{{Ref/Reuse|fs232}}
