Inferra is an advanced planet on the Milky Way galaxy, which resides in the Quintar Alignment territory. It is unknown if it houses a Stargate.
The planet was visited by Vala Mal Doran and her team of smugglers and bounty hunters in order to assist the funeral of Trager Retta and to seemingly retrieve a package. Vala and her team were captured and then escorted to the prison planet Penetera. The planet houses the Inferran Spaceport and is home to countless species. (SG1: "Vala Mal Doran 2")
