51 Pegasi system
51 Pegasi is a stellar system approximately 50.1 light years away from Earth, in the constellation Pegasus. The star's planetary system is home to the planet 51 Pegasi B and its moon Pegasi Delta, whose rich oceans were mined by the Covenant for deuterium and tritium in 2545. The Covenant refinery complex was the target of a UNSC strike in Operation: TORPEDO, which led to the demise of all but two Beta Company SPARTAN-IIIs.
