First mention "Touchstone"

PX3-29A is a planet located in the Milky Way galaxy.


This planet has been visited by SG-1 led by Colonel Jack O'Neill between February 21 and February 22, 1997 according to the archived Stargate power reading reports (SG1: "Touchstone", "The Fifth Race").

Detailled evolution

"Touchstone" (1998)

When Captain Samantha Carter checks out the Stargate uses metalog, the name of the planet is visible on the monitor.

"The Fifth Race"

With the knowledge of the Ancients downloaded into his brain, Colonel Jack O'Neill adds many Stargate addresses on the dialing computer that are not part of the Abydos cartouche chamber. When Captain Samantha Carter checks out for a match, the name of the planet is visible on the monitor.


  • Theoreticaly, one cannot use a symbol twice to dial a gate. Yet the Boötes constellation is called twice in the dialing sequence (fourth and sixth position). Thus, this address is canon yet wrong.
  • According to the dates recorded on the computer, it seems that PX3-29A is one of the first planets visited by SG-1 after Chulak where the first mission occured on February 10 (SG1: "Children of the Gods", "Politics").
