Background information

"AL-tair" was the pronunciation for this system's name from the script pronunciation guide for "Prophet Motive".

According to the first draft of the script for "Amok Time", the other two starships that arrived at Altair were the USS Endeavour and USS Essex. [1]

According to Star Trek: Star Charts (p. 44, "United Federation of Planets I") and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), the primary of the Altair (Alpha Aquilae) system was an A-class star. In the 22nd century, this system was a destination on Earth and Vulcan trade routes. In the late 24th century, the system was largely independent, with only Altair IV listed as a Federation member.

According to the Star Trek Encyclopedia (4th ed., vol. 1, p. 21), the star Altair (Alpha Aquilae) was the brightest star in the constellation Aquila the Eagle. This star was visible from Earth.


According to the video game Star Trek: 25th Anniversary, the USS Constellation and the Klingon flagship, IKS K'lirta, engaged in combat at Alpha Aquila VII, prior to the Organian Peace Treaty.
