Aldebaran's system was inhabited by intelligent and non-intelligent lifeforms. These included Humans, mud leeches, serpents, and shellmouths. (TOS: "Amok Time", "The Deadly Years"; TNG: "Hide and Q"; ENT: "Anomaly")
In 2135, the HMS New Zealand was launched from Earth on a diplomatic mission to Aldebaran's system. It was listed on the chart Interstellar Expeditions to Sectors 184/02-185/38: Launched From Sol System, Earth Dates 2123-2190, which was seen on a screen in Jean-Luc Picard's ready room aboard the USS Enterprise-D.

Background information Edit
For the remastered episode "Up The Long Ladder", Aldebaran replaced Alderaan.
According to Star Trek: Star Charts (p. 62) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), the Aldebaran (Alpha Tauri) system was located in the Beta Quadrant. This was a quaternary star system of three K-class stars and one M-class star. In 2385, this was a UFP system.
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.
