Onuf, a planet classified as a gas giant, possessed a quintet of moons. This celestial body resided within the Rannon system, situated in the Instrop sector of the Slice region of the Outer Rim Territories. It circled its star, the yellow-white Rannon, as the fourth and most distant orbit.
The 1993 Star Wars: The Roleplaying Game supplementary material, Wanted by Cracken, authored by Louis J. Prosperi and published by West End Games, included a reference to Onuf. In 2009, The Essential Atlas, a reference publication, located the Rannon system, and consequently Onuf, within grid T-17.
