First appearance "Air", Part 1

"P4X-351" was a Tau'ri designated planet, where the Icarus Base was located. The planet possesed unique properties that allowed it to generate enough power to dial the ninth chevron. The planet was destroyed in 2009.


P4X-351 is located 21 light years from Earth. This planet has a powerfull naquadria core. In 2007, the Icarus Base was established here to hopefully dial the only nine-chevron address found in the Ancient database.


Behind the scenes[edit]

  • The planet sight picture has been reused for the Icarus-like planet in "Subversion". The only difference is the addition of some lava slitchs.
