Stellar cartography

The Coridan system was visible from Earth in the constellation Orion. This system was approximately 28 light years from Sol.

In the 2150s, this system's position was labeled on an United Earth star chart which was displayed in several crew and guest quarters aboard the Enterprise. (Star Trek: Enterprise, set decoration))

In 2259, the location of this system was labeled on a stellar cartography chart that was seen on the USS Enterprise's ready room viewscreen. This system's symbol had a blue color, indicating that it was affiliated with the United Federation of Planets. (SNW: "Strange New Worlds", "Spock Amok")

On stardate 1292.4, the location of this system was labeled in a chart used during a Section 31 Alpha Team briefing. (Star Trek: Section 31)

Background information

In the script for "Sarek", Coridan was listed in the pronunciation guide, where the term was pronounced "CORE-ah-don".

In a deleted scene from Star Trek Into Darkness, a news feed announced that Magustav Pachangara became the new chancellor of Coridan. This information appeared on a powerwall in the office of Admiral Alexander Marcus. [1]

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, and Star Trek: Lower Decks. The real-world information added to the article was current as of 2025.

The star chart seen in the series Star Trek: Enterprise made its first appearance in Crewman Daniels quarters in "Cold Front". It was also seen in several other episodes of the series, from 2151 to 2154. (For more information, see Federation star charts#United Earth Alpha/Beta star chart)

The current location of Coridan system in the Beta Quadrant was based on the most recent star charts seen in Star Trek: Strange New Worlds and Star Trek: Section 31.
