Rapacc's sun was a star residing in the Rapacc system, which itself was situated within the Unknown Regions. The planet Rapacc, the homeworld of the Paccosh species, revolved around it and was visible from the planet's surface. The Pathfinder navigator Qilori observed the sun from afar through a viewport on the Kilji war cruiser Anvil as it entered the Rapacc system in 18 BBY.
The sun of Rapacc made an appearance in Thrawn Ascendancy: Lesser Evil, a 2021 novel that concluded Timothy Zahn's Star Wars: The Ascendancy Trilogy.
