Stellar cartography

The Cebelrai system was visible from Earth in the constellation Ophiuchus. It was approximately 83 light years from Sol.

In 3191, this system's location was labeled on a star chart. (DIS: "Red Directive")

In 3195, this system's position was labeled on a Federation star chart which was displayed in Starfleet Academy's Stellar Cartography laboratory. (SA: "Beta Test")

Later that year, this system's position was labeled on a Federation star chart which was displayed on the bridge of the USS Athena. (SA: "Come, Let's Away")

In 3196, during the Omega-47 crisis, the location of Cebelrai (Beta Ophiuchi) was depicted on star charts and readouts used across several locations on the USS Athena to locate, monitor, and respond to the Omega-47 mines laid by the Venari Ral. This system was outside the affected region. (SA: "300th Night")

Appendices

Background information

This star system was only mentioned in writing.

The location of this star system was seen on the bridge of the SS Eleos XII on what appears to be an updated chart from Star Trek: Star Charts. Dave Blass published pictures of the set on his website.

Information on this system was derived from the episodes and films, the reference works Star Trek: Star Charts and Stellar Cartography: The Starfleet Reference Library, and real-world sources. The reference works were used extensively in the creation of star charts seen in Star Trek: Discovery, Star Trek: Picard, Star Trek: Strange New Worlds, Star Trek: Prodigy, Star Trek: Lower Decks, and Star Trek: Starfleet Academy. The real-world information added to the article was current as of 2026.

In the real world, Cebelrai is spelled as "Cebalrai".
