Alexandra's Planet

Alexandra's Planet is an inhabitable planet.

On stardate 44765, Elias Vaughn was involved in an encounter with Romulans on Alexandra's Planet after an Iconian gateway was located there, with Vaughn forced to destroy the gateway to stop the Romulans from using it. Vaughn's mission was later classified, although Admiral William Ross provided some redacted information to the crews of the USS Enterprise (NCC-1701-E) and Deep Space 9 in 2376. The information from Alexandra's Planet was helpful to Geordi La Forge, Nog and Thirishar ch'Thane during the Gateways Crisis. (,, SS TNG (The Other Side))
 * Based on the stardate of 44765, the events on Alexandra's Planet occured in 2367, between "Qpid" and "The Drumhead" in TNG's fourth season.
