Category:Planets in the Pegasus Galaxy

The Ancients moved to Pegasus several million years ago in their city-ship Atlantis. They not only created and named their own settlements on various planets, but they also seeded the galaxy with human life. They kept the names and locations of these planets in their sophisticated database in Atlantis, but once the Atlantis Expedition arrived 10,000 years after the Ancients abandoned the city, the planets were given alphanumeric designations, such as M6H-987, by their Stargate dialing interface program. This same computer system was developed by Stargate Command (SGC) because they didn't have a Dial Home Device (DHD), but it was later used at every off-world base, even when a DHD was present, because the interface gave base personnel better control over the use of their Stargates.
