PB5-926 was a planet in the Milky Way galaxy which contained a Stargate. SG-1 visited this planet looking for the Tok'ra, but were instead surprised when Apophis crash landed on the planet in a Death Glider and asked for their help. The team proceeded to take Apophis from the planet to Earth. They later sent Apophis' body back to the planet through the Stargate to stop Sokar's attack on Earth. (SG1: "Serpent's Song")
