The Pléiades system was designed under the French-Italian ORFEO Programme (Optical and Radar Federated Earth Observation) between 2001 and 2003. [2]The Pléiades programme was launched in October 2003 with CNES (the French space agency) as the overall system prime contractor and EADS Astrium as the prime contractor for the space segment.
Star map with the Pleiades (upper right) and the Hyades (centre, V-shaped head of the constellation Taurus with its main star Aldebaran, γ Tauri und ε Tauri (Ain)) at both sides of the ecliptic line (dashed red). The Golden Gate of the Ecliptic is an asterism in the constellation Taurus that has been known
The 2007 new Hipparcos reduction gives a statistically more accurate parallax of 8.51 ± 0.28 mas, indicating a distance of 118 ± 4 pc. [2] Analysis of Gaia parallaxes for the whole Pleiades cluster give an average distance of 136.2 ± 5.0 pc , [ 19 ] while VLBI measurements of multiple members give a distance of 136.2 ± 1.2 pc .
Pleiades seen with the naked eye (upper-left corner). [1]The high visibility of the star cluster Pleiades in the night sky and its position along the ecliptic (which approximates to the Solar System's common planetary plane) has given it importance in many cultures, ancient and modern.
