Stellar cartography
The 36 Ursae Majoris system was visible from Earth in the constellation Ursa Major. It was approximately 42 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)
This star system was only mentioned in writing.
Information on this system was derived from 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)
