Geonosis had a large diameter but light gravity and dense atmosphere. With a weak magnetic field, harsh solar radiation storms were common, and on occasion mass extinctions occurred. The most persistent surface organisms were humble red rock algae while the semi-insectoid Geonosians were driven underground. It consisted of a diminutive molten core with a rocky mantle forming a rocky, desert world subject to flash floods that carved great highland canyons. Water made up 5% of the surface.
During the time of the Geonosian rule, much of the planet's architecture was similar in appearance to termite mounds, consisting of domes and buildings built into caverns and rock spires. Therefore, one could easily mistake Geonosian buildings for natural formations and the planet uninhabited, a great asset during war.
In the distant past, Geonosis's largest moon was hit by a rogue comet, sending out a massive debris field that hammered the surface into ruin, before settling into a ring of orbiting rock. This event killed off more than 99% of Geonosis's native species.
Over millions of years, the few creatures who survived the devastation slowly reclaimed the planet. Random meteor impacts constantly weeded out the weaker species, leaving only the truly cunning, hardy, and ruthless species alive. The Geonosians, the dominant life form on the planet, constituted all three.
During the time of the Great Galactic War, Geonosis was famous for the gladiatorial games held on the planet. Many of the combatants were Mandalorians, among them a young fighter. He rose to fame, eventually declaring himself the new Mandalore. He allied the Mandalorians with the Sith Empire, striking against the Galactic Republic.
Years later, after his eventual death at the hands of another Mandalorian, it was revealed that Imperial Intelligence had been infiltrating the gladiatorial arenas around the galaxy as sponsors, managers and gladiators. They had chosen the young Mandalorian as their champion, rigging his fights, using tactics such as drugging the opponent.
In 24 BBY, during the reign of Archduke Poggle the Lesser, Geonosis became a member of the Confederacy of Independent Systems, which used the planet's factories to build its droid army. Two years later, in 22 BBY, Poggle scheduled a private meeting of the Confederacy leaders on Geonosis. It was expected that during this meeting the organizations that formed the backbone of the Separatist movement would put their resources at the disposal of Count Dooku, the Head of State of the Confederacy.
Unbeknownst to the Separatists, their plans of waging war against the Galactic Republic were heard by Jedi Knight Obi-Wan Kenobi, who had followed Jango Fett, a bounty hunter employed by Dooku, to Geonosis. Kenobi managed to transmit his discoveries to his Padawan Anakin Skywalker, who was at that time located on Tatooine, before being caught by the Separatists. After retransmitting the information to the Jedi Council, Skywalker and Padmé Amidala, the Senator of Naboo, decided to rescue Kenobi, but ended up imprisoned themselves.
Eventually, Kenobi, Skywalker and Amidala were taken to the Geonosian execution arena and were faced against an Acklay, a Reek and a Nexu respectively, but managed to free themselves. The Separatists, in turn, introduced battle droids to the arena, triggering the First Battle of Geonosis, the first battle of the Clone Wars, as Jedi reinforcements, led by Master Mace Windu, revealed themselves among the public and entered the arena to confront the droids. After a long battle between the droids and the Jedi, Grand Master Yoda arrived with the newly-formed Republic army and rescued the defeated Jedi forces. Following the Confederacy's subsequent defeat on the planet, Geonosis was occupied by the Republic, and kept under strong control.
Some time later, plans for a new droid foundry funded by Senator Rush Clovis and the Banking Clan were uncovered by Senator Amidala, leading up to another battle on the planet. Jedi Masters Ki-Adi-Mundi, Obi-Wan Kenobi and Jedi Knight Anakin Skywalker led an assault on Geonosis to destroy Poggle the Lesser's new droid foundry. However, the factory turned out to be very heavily guarded, and the assault met with heavy losses of men and material. Shot down and cut off from each other, Skywalker, Kenobi and Mundi were forced to fight their way to their first prime objective: an assault staging area.
Skywalker and Tano ended up going through a canyon where a fortress had been erected. They destroyed it in the process. They discovered Master Mundi, who had made his way through a tunnel that ended up in him losing many men. Kenobi was no better off. His perimeter was being actively destroyed by the Bug forces and AAT tanks. Skywalker called in reinforcements and destroyed the Geonosian forces. From there Skywalker and his Padawan sacked the shield generator with one swift stroke.
Luminara Unduli and Barriss Offee showed up to help take the factory down. They lead a full frontal assault while the Padawans found their way through the catacombs under the factory where Poggle and a new "super tank" found them and went to take their bombs that they had set on the Main Reactor. Outside, the tactical droid had sent out a dozen tanks to rupture them. They were all destroyed by a sense of ingenuity by the Jedi Masters. The Padawans took the Reactor out with a Super Tank missile and almost sacrificed themselves to do it. They were rescued in the end by their masters.
As the Clone Wars ended and the Republic restructured into the Galactic Empire, Geonosis remained under Imperial control. Geonosian scientists played a role in the construction of the first Death Star. In 3 ABY While chasing an Imperial carrier that had interfered with the Rebel Alliance's raid on the Empire's operations on Bakura, Wedge Antilles visited Geonosis and found several completely operational B1 battle droids left over from the war, as well as a Jedi starfighter, which he used to escape the planet. Soon after, the Droid operations where put down by the Galactic Empire, which ultimately brought an official end to the Separatist holdouts. During that battle, three Imperial Escort Carriers ended up being destroyed. Sarkli took cover from the Battle droids in a crashed, but woking, LAAT/i The surviving stormtroopers were killed by the battle droids. After the death of Emperor Palpatine, Geonosis established an isolationist policy.
Geonosis is the only planet featured in the Star Wars films to have a natural ring system.
Geonosis was a planet in the Outer Rim. While not a participant, Nathaniel Kenobi was greatly effected by the battle started there in the Clone Wars.
