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

In the summer of [[2552]], the [[Covenant]] invaded the system and attacked Epsilon Eridani's major colonies. Reach ultimately [[Fall of Reach|fell]] to the Covenant and was [[Glassing|glassed]],<ref>[https://www.halowaypoint.com/en-us/universe/locations/reach ''Halo Waypoint'': Reach]</ref> while [[Tribute]] was brutally [[Battle of Tribute|assaulted]] and partially glassed.<ref name="h4evg2">''[[Halo 4: The Essential Visual Guide]]'', p. 177</ref> Following the [[Human-Covenant War]], at least Tribute and [[Beta Gabriel]] had been resettled by humanity.<ref>''Halo: First Strike'', [[Tug o' War]] (2010)</ref><ref name="universe">[https://www.halowaypoint.com/en-us/universe/locations/tribute ''Halo Waypoint'': Tribute]</ref><ref name="h5">''[[Halo 5: Guardians]]'', multiplayer level, [[Fathom]]</ref>

By the early 21st century, scientific observation had deduced the presence of an inner rocky asteroid belt, an outer icy belt, and at least three planets: a gas giant the size of [[Jupiter]], and possibly two terrestrial planets, near the inner and outer belts, respectively.<ref>[[Wikipedia:Epsilon Eridani|''Wikipedia'': Epsilon Eridani]]</ref> 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 marshalling 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 name="universe"/>

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>''Halo Encyclopedia (2011)'', p. 43</ref> 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, with Circumstance following shortly after.<ref name="universe"/> 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 name="bnet"/>

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>''Halo: Reach'', campaign level, [[Winter Contingency]]</ref> Soon after [[Teller Station]] of [[Site 17]] in the system's Oort cloud was attacked by the fleet.<ref>''[[Halo: Fleet Battles]]'', [[Scenario Three: Evacuate]]</ref> At the same time as these events, the other colonies of Epsilon Eridani came under assault by the Covenant.<ref name="universe"/> By August 30, Reach was glassed.<ref>''[[Halo 2: Anniversary]]'', campaign level, [[The Heretic]]</ref><ref>''[[Halo: Reach]]'', campaign level, [[The Pillar of Autumn (Halo: Reach level)|The Pillar of Autumn]]</ref> Combat continued on and around Tribute up until around November 2, when Covenant forces began [[Great Schism|attacking one another]].<ref name="universe"/>

Between [[2555]] and [[2558]], UNSC [[Central Command|CENTCOM]] for Region One enter into negotiations with [[Covenant remnants]] around Tribute.<ref>''[[Halo 5: Guardians Limited Edition]]'', Spartan Locke's Classified Orders</ref> By [[2589]], the planet had returned to a livable state and continued to see an influx of new colonists.<ref name="hrlonewolf">''Halo: Reach'', campaign level, [[Lone Wolf]]</ref>

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>''Halo: First Strike'', p. 232</ref> At least five of the worlds that orbit Epsilon Eridani are known to be inhabited.

*Epsilon Eridani I - Closest planet to the star.{{Ref/Note|Name=DesignationNotName|This planet is only known by its astronomical designation, not its colloquial name. Consequently, this planet may in fact be one of the three planets whose colloquial names are known but whose astrononical designations are not: Beta Gabriel, Circumstance and Tantalus.}}

*[[Reach]] {{C|Epsilon Eridani II}} – The former military center of the UNSC, and the most developed human colony. Glassed in 2552 but at least partially habitable by [[2589]].<ref name="hrlonewolf"/>

**[[Turul]] {{C|Epsilon Eridani IIa}} - The smallest of Reach's two moons, with the shorter orbital radius.

**[[Csodaszarvas]] {{C|Epsilon Eridani IIb}} - The larger of Reach's moons, with a longer orbital radius.

*[[Tribute]] {{C|Epsilon Eridani III}} – A major human colony, known for its strong industrial capacity and large population.<ref>''[[Halo: Contact Harvest]]'', Prologue</ref> Partially glassed during the [[Battle of Tribute]], under UEG control as of [[2558]].

**[[Emese]] {{C|Epsilon Eridani IIIa}} - Tribute's sole natural satellite.

*[[Epsilon Eridani IV]] – Known to be the site of an [[Insurrection]].<ref>''[[Halo Wars: Official Strategy Guide]]'', p. 22</ref>{{Ref/Reuse|Group=Note|Name=DesignationNotName}}

*[[Beta Gabriel]] {{C|Unknown orbital position}} – Largely uninhabited, converted into an outdoors resort by wealthy entrepreneurs. Occupied by a [[Jiralhanae|Brute]] [[pack]] during or otherwise soon after the Fall of Reach.<ref>''[[Halo: The Fall of Reach]]'', p. 324</ref><ref>''[[Halo: Evolutions - Essential Tales of the Halo Universe]]'', "[[Stomping on the Heels of a Fuss]]"</ref>

*[[Circumstance]] {{C|Unknown orbital position}} – A world-famous for its universities and courts of justice. Status unknown.<ref>''[[Halo: Contact Harvest]]'', p. 62</ref>

*[[Tantalus]] {{C|Unknown orbital position}} – A human colony with an unknown status after the Covenant's siege in the system.<ref>''[[Halo Encyclopedia]]'', p. 287</ref>

**Unidentified planetoid - A [[Wikipedia:Planetesimal|planetesimal]] located within the Oort cloud, which once had a Forerunner presence.

***[[Site 17]] - A Forerunner site on the planetoid.

***[[Teller Station]] - An [[Office of Naval Intelligence|ONI]] research facility set up to study Site 17.
