|Out of Universe informations|
PX3-99 is a planet located in the Milky Way galaxy.
During their search of Colonel Jack O'Neill and Captain Samantha Carter, who were missing in action, Stargate Command put a mission to try to locate them, as it is a planet located between Earth and P4A-771, from where SG-1 ran of. According to Doctor Daniel Jackson and Sergeant Siler, as Stargates are basically giant superconductors, it could discharge the matter stream on another Stargate between Earth and P4A-771.
- The planet's name isn't spoken in the episode. It only appears on the galaxy map in Stargate Command.
