Epsilon Eridani system

Not to be confused with Eridanus System The Epsilon Eridani System is 10.5 light years from Earth and is in FLEETCOM Sector One. It is home to several habitable planets, and until 2552 the most notable was Reach. At 10.5 light years from the Sol System, it is one of the closest neighbors of humanity's homeworld.

Epsilon Eridani's superior interstellar jump point had been the most active Slipstream Space transfer zone (arrivals and departures) for over thirty years, with ε Eridani's inferior IJP and Sol's superior IJP regularly trading second and third place spots.

Humans held the system for several hundred years, until the Battle of Reach in 2552. After that, the system came under control of the Covenant. It was home to many of the UNSC's strongholds and military bases, such as Reach.

It was protected by the UNSC Epsilon Eridani Defense Fleet.

Colonies
Epsilon Eridani is home to several planets, with at least three of them known to be inhabited;
 * Epsilon Eridani B - a gas giant discovered in 2000. Likely renamed after system colonization.
 * Epsilon Eridani IV - known to be the site of an Insurrection.
 * Reach - the former military center of the UNSC, and the most developed UNSC colony. Glassed by the Fleet of Particular Justice in 2552.
 * Circumstance - famous for its universities and courts of justice. Status unknown.
 * Tribute - a recently set up colony, known for its industrial capacity. Status unknown.
 * Beta Gabriel - largely uninhabited, converted into an outdoors resort by wealthy entreprenours. Occupied by a Brute pack soon after the Battle of Reach.

Real Life
Scientific observation has 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.
