Lambda Serpentis (Earth-5875)

The Lambda Serpentis system is a planetary system which orbits the giant yellow G-type star better known as Jericho. It is located approximately 38-light years away from the Sol system.

History
In 2535, the system was invaded by the Covenant, who attacked the human Outer colony Jericho VII. While the UNSC dispatched many SPARTAN-IIs to defend the planet, the Covenant forces proved too much and Jericho VII was eventually glassed.

In 2552, a Covenant fleet was sent to the Lamba Serpentis system to collect tritium for the reactors of the Unyielding Hierophant.
