KS7-535 is a frozen planet, apparently with no dial home device (DHD). Anubis escaped Stargate Command by possessing various people. He dialed the Stargate, and eventually left in Colonel Vaselov's body. Although they could not stop the dialing program, Col. Carter was able to reroute the wormhole to KS7-535.
Anubis/Vaselov was left on this chilly world wearing nothing but hospital scrubs and no way off. Anubis eventually somehow escaped the planet, but Vaselov apparently died.
