P2M-903 was a planet designated by the Tau'ri in the Milky Way Galaxy. This was one of the planets that was a refuge and capital stronghold for one of the Ba'al clones and brainwashed Jaffas under the control of the Goa'uld Empire-in-exile. His Ha'tak sat perched on a pyramid near a hillside, visible a half mile from the Stargate. Ba'al established a perimeter of ground troops and two cannons to defend the landed mothership from forces who might arrive through the Stargate.

The pyramid, guarded by at least two Jaffa, contained a Transportation rings platform for entry into the ship. (SG1: "Stronghold")
