Background information

According to, the primary of the Aldebaran system was named Aldebaran (Alpha Tauri). It is a spectral type K5 star located 68 light years from Sol. It is one of the brightest stars in Earth's night sky. [1]

For the remastered episode "Up The Long Ladder", Aldebaran replaced Alderaan.

In the Star Trek: Star Charts (p. 62) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), Aldebaran (Alpha Tauri) is a multi-star system with a trio of K-class stars and one M-class star. In 2385, this is a Federation system.

A scene from the script of TNG: "The Dauphin" would have had the Enterprise scheduled to visit a place called Aldebaran Zeta.

In the first draft script of ENT: "Strange New World", Travis Mayweather told a ghost story about a brain-sucking carnivore on a planet in the "Aldeberan system", though T'Pol refuted the tale, saying there were no such lifeforms in that system. During the episode's development, this ghost story instead became one about George Webb.
