Classified as an F-type star, Orellius Minor was the primary of the Orellius system. This system was near the Bajoran wormhole.

In 2370, Commander Benjamin Sisko and Chief Miles O'Brien encountered an uncharted Human colony on a class M planet in the system. Alixus, the leader of the colony, attempted to destroy their runabout, the USS Rio Grande, by sending it into Orellius Minor. However, as the trajectory was off, the gravity flux of the star deflected the runabout. The runabout was later sighted in open space by the Romulan vessel Gasko. (DS9: "Paradise")

According to the script, Orellius was pronounced as "ohr-REHL-ee-uhs".
