From Halopedia, the Halo wiki

The Democritus was a remote scanning outpost located in the Sol system, in orbit around Pluto.[1]

Service history[edit]

Battle of Earth[edit]

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


The station was likely named after the Greek philosopher and astronomer of the same name.
