The 51 Pegasi system is a planetary system home to the planet 51 Pegasi B and its moon Pegasi Delta,[1] 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.[2]
