The '''Epsilon Eridani system''' (sometimes rendered '''ε Eridani'''){{Ref/Generic|Halo: Reach|[[:File:Recon smg.jpg|Recon armor bonus content]]}} is a planetary system situated 10.5 light-years from [[Earth]],{{Ref/Reuse|Enc09}}{{Ref/Reuse|enc298}} and is identified as a region in [[FLEETCOM Sector One]].{{Ref/Reuse|for343}} It was home to several habitable [[planet]]s [[Human colonies|colonized]] by the [[Unified Earth Government]], most notably [[Reach]]. At 10.5 light-years from its sister system, the [[Sol system]], it is one of the closest neighbors of [[human]]ity's [[Earth|homeworld]].{{Ref/Reuse|bnet}}

In the summer of [[2552]], the [[Covenant]] invaded the system and attacked Epsilon Eridani's major colonies.

==Overview==
===Planetary system===
The Epsilon Eridani system is home to at least six planets, two [[asteroid]] belts, and at least one [[Wikipedia:Minor planet|minor planet]]. A massive [[Oort cloud#Epsilon Eridani system|Oort cloud]] is located on the outer edge of the system.{{Ref/Novel|Halo: First Strike|Page=232}} At least five of the worlds that orbit Epsilon Eridani are known to be inhabited.

==History==
===Early history===
The first planetary confirmations of planet Reach in Epsilon Eridani occurred in the 21st-century.{{Ref/Reuse|bnet}}

The Epsilon Eridani system was recognized to have an improbably high number of habitable planets, a fact that was seen as serendipitous to the early colonization efforts. Initial colonization efforts in the system faced significant challenges in marshaling political and economic support. Interest in the system's colonization potential initially focused on [[Tribute]] and [[Circumstance]], though it was [[Reach]] that would soon capture the attention of UEG planners.{{Ref/Reuse|universe}}

===Colonization and human hold===
{{Main|Project OUTBOUND}}
The system was originally colonized by the colony ship ''[[Odyssey]]'' with the first wave of humanity's extrasolar colonization in [[2362]], landing on Reach.{{Ref/Book|Halo Encyclopedia (2011)|Page=43}} Beta Gabriel would be settled in [[2363]].{{Ref/Book|Id=Enc22|Enc22|Page=50-51}} Afterwards, Tribute was colonized on [[2364|August 8, 2364]] when {{CAAShip|Casbah}} arrived and established the initial navigation and communication satellite constellation on the planet,{{Ref/Reuse|universe}} with Circumstance being settled the same year.{{Ref/Reuse|Enc22}}

By [[2390]], the bulk of the UNSC's administrative and technical infrastructure was moved to the system. Corporate investments followed, with the construction of the first extrasolar shipyard facilities and material refineries.{{Ref/Book|Enc22|Page=42}}

By the late 25th century, the system had become home to many of the [[United Nations Space Command|UNSC]]'s strongholds and military bases, such as Reach. It was protected by the UNSC [[Epsilon Eridani Fleet]]. Before the [[Fall of Reach]], Epsilon Eridani's superior [[interstellar jump point]] had been the most active [[Slipstream space]] transfer zone (arrivals and departures) for over thirty years, with Epsilon Eridani's inferior IJP and Sol's superior IJP regularly trading second and third place spots.{{Ref/Reuse|bnet}}

===System wide assault===
{{Main|Fall of Reach|Battle for Tribute|Battle of Beta Gabriel}}
In [[2552]], the system came under attack by the Covenant. Initially, the [[Fleet of Valiant Prudence]] made landfall on Reach triggering [[WINTER CONTINGENCY (protocol)|WINTER CONTINGENCY]].{{Ref/Level|Halo: Reach|[[Winter Contingency]]}} Soon after [[Teller Station]] of [[Site 17]] in the system's Oort cloud was attacked by the fleet.{{Ref/Generic|[[Halo: Fleet Battles]]|[[Scenario Three: Evacuate]]}} At the same time as these events, the other colonies of Epsilon Eridani came under assault by the Covenant.{{Ref/Reuse|universe}} By August 30, Reach was glassed.{{Ref/Level|[[Halo 2: Anniversary]]|[[The Heretic]]}}{{Ref/Level|[[Halo: Reach]]|[[The Pillar of Autumn (Halo: Reach level)|The Pillar of Autumn]]}} Glassing would cease on September 27, when ships would be pulled away to be redeployed to Tribute or to prepare for the coming [[Battle for Earth|invasion of Earth]].{{Ref/Reuse|Enc22}} Combat continued on and around Tribute up until around November 2, when Covenant forces began [[Great Schism|attacking one another]].{{Ref/Reuse|universe}}

===Post-attack===
{{Main|Operation: WOLFE}}
Between [[2555]] and [[2558]], UNSC [[Central Command|CENTCOM]] for Region One entered into negotiations with [[Covenant remnants]] around Tribute.{{Ref/Generic|[[Halo 5: Guardians Limited Edition]]|Spartan Locke's Classified Orders}}

By [[2589]], Reach had returned to a livable state and continued to see an influx of new colonists{{Ref/Level|Id=hrlonewolf|Halo: Reach|[[Lone Wolf]]}} with some [[city|cities]] being populated again around [[2610]].{{Ref/Generic|[[Halo: Reach Legendary Edition]]|[[:File:Journal Package Letter.jpg|package contents letter]]}}
