Yibikkoror was a planetary body within the Yinchorri system, as documented in Legends materials. This world was diminutive in size, characterized by a thick atmospheric envelope and potentially lacking any solid ground. The Yinchorri constructed at least one balloon city upon this planet, and its inhabitants employed flutter-packs as a means of getting around. The Battle of Yibikkoror took place here in 33 BBY during the historical event known as the Yinchorri Uprising.
According to The New Essential Chronology, Yibikkoror is described as a satellite orbiting Yinchorr; however, Jedi Council: Acts of War establishes that it is, in fact, a planet.
