What is the name of the planet where the Geonosian droid factory is located in Episode II?

The story behind the answer

Because Episode II’s droid assembly lines and the arena rescue take place on the arid, hive-built homeworld of the winged Geonosians, overseen by Archduke Poggle the Lesser. That distinguishes it from Kamino (the storm-lashed ocean planet with the Republic’s clone facilities), Naboo (lush homeworld of Padmé and the Gungans), and Mustafar (the lava world central to Episode III’s duel, not Episode II’s factory).

Historically, this planet is pivotal: the Battle fought there kicks off the Clone Wars, and its leaders secretly transfer the early Death Star schematics to Count Dooku. The Geonosians’ industrial prowess and separatist alliances made their foundries the backbone of the Confederacy’s droid armies.
