P3X-118 is a planet in the Milky Way galaxy which held a Stargate and is home to an alien species known as the Stragoth. The Tau'ri visited this planet in 1999, sending SG-6, though the mimetic aliens managed to capture and impersonate the team.
These impersonators came through the Stargate to Earth, where they managed to take over Stargate Command by impersonating all of its personnel while keeping the real personnel heavily sedated.
After the Tau'ri managed to stop their invasion, Major General George S. Hammond, the commander of the SGC ordered that P3X-118's address be permanently locked out of the SGC's dialing computer, declaring the planet off-limits to all SGC personnel. (SG1: "Foothold")
