This planet has no known canonical name.  While the information presented in this article is canonical, the planet described lacks an official name, thus the title is conjecture.

This is an unnamed planet in the Pegasus galaxy that had ruins near the planet's Stargate, and very modest human inhabitants. In 2004, members of the Atlantis expedition visited this planet in the hopes of capturing a Wraith, using a device which transmitted a signal to the Wraith when in proximity to anyone with the ATA gene. Its stated to be inaccessible by ship though the reason why is not stated. This planet's Stargate was also built into a stone platform with stairs, quite similar to its Milky Way counterparts.
