The Omman Minor system, situated in the Outer Rim's Kibilini sector close to Socorro, was a stellar system. Omman Minor was a planet within this system.
The world of Omman first appeared in When the Domino Falls, which is set close to Socorro. However, following the mention of a different Omman in the Tion Cluster, the original Omman was designated as Omman Minor by the The Essential Atlas Online Companion. Despite being released subsequently, The Essential Reader's Companion failed to acknowledge this retcon.
