The Eridanus sector is a sector of space as classified by the UNSC. The sector presumably consists of several planetary systems in the Eridanus constellation, including Eridanus and Epsilon Eridani. The colony world of Mamore is also located in the sector, though the system in which it is situated is unknown. The Eridanus sector was the site of many battles between the UNSC and the rebels during the Insurrection.[1]
