Wikipedia There is more information available on this subject at Lambda Serpentis system on the English Wikipedia.

Lambda Serpentis is a star system composed of a yellow G-type star, located around 38 light-years from the Sol system. Lambda Serpentis was formerly the location of at least one of the UNSC's outer colonies, a planet in the system contained the Jericho VII colony.[1]

History Edit

In 2535, the Covenant invaded the system and attacked the UEG colony on Jericho VII. Even though the UNSC sent SPARTAN-IIs to help defend Jericho VII, the human defenses were overwhelmed and the Covenant glassed the planet. In 2552, a Fleet of Covenant ships were ordered to go to the Lambda Serpentis system to collect Tritium gas for their reactors in preparation to rendezvous with the Unyielding Hierophant and mass Slipspace jump to Earth, indicating that the system is now home to a Covenant refueling station at the very least.[2]


  • While described as having two reddish suns in The Fall of Reach, the real-world Lambda Serpentis system only has a single, yellow star.
