P5R-221

P3X-1492 was a planet in the Milky Way galaxy which held a Stargate. At some point in time, it was seeded with Humans by the Goa'uld, but they only managed to last around three or four generations before dying out. It was visited in the early years of the Stargate Program by SG-8, who were doing scientific studies there and trying to find out whether the previous inhabitants had died out due to climatic changes or if they simply never adjusted to the new planet.
