Taygeta is one of the main stars in the Pleiades Cluster. It is a triple star system, consisting of Taygeta A (which in itself is a close binary) and Taygeta B (a distant binary of A). They are approximately 440 Light Years away from earth. 
The primary component, Taygeta A, is a blue-white B-type subgiant with an apparent magnitude of +4.30. It is a spectroscopic binary, whose component stars have magnitudes of +4.6 and +6.1. They are separated by 0.012 arcseconds and complete one orbit every 1313 days. They have an 8th magnitude companion, Taygeta B, 69 arcseconds away.

According to Billy Meier, one of its planets is called Erra, and this would be the planet his main Pleiadian contact, Semjase, originated from.

Other sources, too, refer to contacts with Pleiadiansfrom the Taygeta system.
