Stellar cartography

The Dessica system was visible from Earth in the constellation Virgo. It was approximately 110 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 green color, indicating that it was affiliated with the Romulan Star Empire. (SNW: "Strange New Worlds", "Spock Amok")

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

The system's location was labeled in a Federation star chart that was in Fleet Admiral Kirsten Clancy's office at Starfleet Headquarters in 2399 and on the bridge of the USS Titan-A in 2401. Dessica was in or near to space claimed by the Romulan Free State. (PIC: "Maps and Legends", "The Next Generation", "Disengage")

This star system was only mentioned in writing.
Information on this system was derived from the episodes, 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
