Pleiades Cluster

The Pleaides Cluster was a grouping of stars in the Milky Way Galaxy. They were easily visible from Mars.

In 2364 the USS Enterprise (NCC-1701-D) was on a mapping mission of the cluster before being diverted to Velara III. 

The Doctor pointed out the Pleaides to Denara Pel when they participated in a romantic holodeck program of a drive on Mars.
