Democritus was the name for a Remote Scanning Outpost in the Solar System. Democritus was in orbit around Pluto, the ninth planetary body in the system.

Operational HistoryEdit

This station was undetected by the Covenant as long as November 3, 2552, during the Battle of Earth. It was thus, still functional. It monitored Slipspace activity and picked up a message sent from Cortana using Forerunner technology and another signal piggybacked on it by Dr. Catherine Halsey.[1]
