The Lambda Serpentis System is a star system in the constellation Serpens. It is 38.3 light years from the Sol System and was formerly a part of the UNSC's outer colonies. At least one planet in the system was colonized by humans at one time: the planet Jericho VII.
In 2525, the UNSC Atlas went on a patrol in this system. In 2535, it fell to the Covenant and Jericho VII was glassed.
In 2552, a fleet of Covenant ships was ordered to go to the Lambda Serpentis system to collect Tritium gas for their reactors in preparation to rendezvious with the Unyielding Hierophant and mass Slipspace jump to Earth.
The system is currently considered to be Neutral.
