P3A-575 (sometimes called P3-575) was one of the first planets the SGC's computer was able to find after the first missions to Abydos and Chulak. The Abydos Cartouche listed several addresses, and P3A-575 and P3A-577 were the first planets Captain Carter's team was able to recalculate after allowing for stellar drift.
Col. O'Neill and Maj. Kawalsky, the leaders of SG-1 and SG-2, good-naturedly teased about which team would take which mission before Gen. Hammond stepped into the conversation. Later, General Hammond mentioned Col. O'Neill's team would be the one to go to P3A-575.
When it was discovered that Major Kawalsky was infected by a Goa'uld, SG-1 was focused on that crisis and any missions were put on hold. After Kawalsky's death, the mission was again a go. Because of Teal'c's selfless actions during the crisis, he was able to gain the American military's trust and became a member of SG-1. P3A-575 was SG-1's first mission as a four member team, but the results of their reconnaissance are unknown.
