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.

"I can tell you about a planet where there is a device created by the Ancients."
Camulus tells Jack O'Neill about the planet.[src]

Planet (Zero Hour) is a planet in the Milky Way galaxy which has a Stargate, formerly under Camulus' control. SG-3 was sent to the planet after the Goa'uld Camulus informed Colonel Jack O'Neill that there was a Zero Point Module there that was connected to a Ancient device, and that the planet was once an main base of the Ancients.
