|First mention||"The Enemy Within"|
P3-575 is a planet located in the Milky Way galaxy.
This planet is one of the first submitted by Captain Samantha Carter's team according to the map found by Daniel Jackson on Abydos in the cartouche chamber (SG1: "Children of the Gods", "The Enemy Within").
General Hammond is briefing SG-1 and SG-2 about P3-575 and P3A-577, two planets submitted by Captain Carter's team as possible destinations. Those planets will be visited concurrently by SG-1 and SG-2. Colonel O'Neill and Major Kawalsky tease each other about who goes where. As General Hammond put things straight, an alarm is blowing in the Stargate Command control room.
When the alarm is off, Hammond decides to give to SG-2 (led by Kawalsky) the P3-575's mission.
Later, after Kawalsky's unfortunate death because of a Goa'uld symbiote who has taken Kawalsky's body, SG-1 has a go for a recon mission on P3-575. According to the MALP, conditions for the planet are favorable.
