Not to be confused with Eridanus system

The Epsilon Eridani system is 10.5 light years from Earth and in FLEETCOM Sector One. It is home to several habitable planets 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.


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.[1]

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.[2]

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. Prior to its loss, the system 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.


Epsilon Eridani is home to several planets, with at least six of them known to be inhabited;
