Eridanus II

Eridanus II is a planet in the Epsilon Eridani Star System (which, including Eridanus II has a total of 12 planets.)

Background
A UNSC colony world, little has been revealed about this planet, but it is the location of the Luxor Spaceport and Elysium City, where John-117 grew up until he was abducted and sent into the Spartan program in 2517. It is also to be noted that it is a place of much hostility against the UNSC, as Dr. Halsey stated many pirates and rebels were operating from the system. John later returned there in 2525 with the other Spartans aboard the destroyer UNSC Pioneer to board the cargo freighter Laden and travel to a rebel base, Eridanus Secundus in the system's asteroid field.

The Spartans later returned to the system in 2552 aboard the captured Covenant flagship Ascendant Justice, returning to the Rebel base.

Though there is some debate as to the nature of the planet, there is nothing to actually suggest that Eridanus II was a gas giant; rather there is a separate gas giant in the system that Dr. Halsey used for a slingshot maneuver on her approach to the planet. She did mention "climate-controlled weather", from which one might infer domed environments, although this does not necessarily suggest a world without a breathable atmosphere.

The colony of the planet was destroyed by the Covenant in 2530.

Trivia
It is probably a play on Eta Eridani a real life star that translates as "Hatching Place" or "Breeding Place". It is also John 117's home world.
