Pleiades Cluster

The Pleiades Cluster, also known as Messier 45, was a star cluster in the Alpha Quadrant. This star cluster was located in the constellation Taurus and was approximately 417 light years from Sol. The planet Velara III was near to this cluster. (TNG: "Home Soil")

An image appearing to be this cluster was contained in the Enterprise computer in 2254, when the Talosians scanned the recordings of the USS Enterprise. (TOS: "The Cage")

On stardate 41463.9, the USS Enterprise-D was mapping the cluster. During the mission, the Enterprise-D was asked by the Federation to visit terraformers on Velara III. Soon after resolving a conflict with microbrain, the lifeform native to Velara III, the Enterprise-D returned to an unnamed starbase with the surviving terraformers. (TNG: "Home Soil")

While on a date, on a holographic re-creation of Mars, with Danara Pel, The Doctor pointed out the Pleiades Cluster as among the many star formations and astronomical highlights seen from the surface of the planet. (VOY: "Lifesigns")

Background

In Star Trek: Star Charts ("United Federation of Planets II"), the Pleiades Cluster was located in the Alpha Quadrant. The quadrant of origin for this stellar cluster was based on its real-world placement, which aligned with what was stated in the Star Trek: Star Charts.

Information on this cluster was derived from the episode and from real world sources.

An unused image of the Talos IV surface prepared for "The Cage" showed the Pleiades very prominently in the Talos sky, the brightest stars enlarged to the size of suns. [1] It would seem that the image from "The Cage" would suggest that Talos IV was located in this cluster. (Star Trek Encyclopedia, 4th ed., vol. 2, p. 171)

In the Star Trek Encyclopedia (4th ed., vol. 2, p. 171), the Pleiades, also known as M45 or the Seven Sisters, was described as a [[[space|spatial]] region with young planets. It was a "cluster of about 400 stars in a 25-light-year radius, some 415 light years from Earth."

In StarTrek.com, the Alcyones were from Alcyone. [2](X) This star was found within the Pleiades cluster.
