51 Pegasi system

51 Pegasi is a system approximately 50.1 lightyears away from Earth, in the constellation Pegasus. The stars planetary system was controlled by the Covenant during 2545, and was home to 51 Pegasi B and Pegasi Delta, used by the Covenant in mining deuterium and tritium in the planetoid's rich oceans.

51 Pegasi was the very first main sequence (sun-like) star discovered to have a planet in orbit around it.
