The Pleiades (/ ˈ p l iː. ə d iː z, ˈ p l eɪ-, ˈ p l aɪ-/), [8] [9] also known as Seven Sisters and Messier 45 (M45), is an asterism of an open star cluster containing young B-type stars in the northwest of the constellation Taurus.
The two satellites operate in the same phased orbit and are offset at 180° to offer a daily revisit capability over any point on the globe. The Pléiades also share the same orbital plane as the SPOT 6 and 7, forming a larger constellation with 4 satellites, 90° apart from one another. [5] Orbit: Sun-synchronous, phased, near-circular

The Golden Gate of the Ecliptic is an asterism in the constellation Taurus that has been known

When Black God entered the hogan of creation, the Pleiades were on his ankle; he stamped his foot and they moved to his knee, then to his ankle, then to his shoulder, and finally to his left temple.
They are used to identify and locate constellations, stars, nebulae, galaxies, and planets. [1] They have been used for human navigation since time immemorial. [ 2 ] Note that a star chart differs from an astronomical catalog , which is a listing or tabulation of astronomical objects for a particular purpose.

In 1996 a group of Japanese and French astronomers discovered that Pleione is a single-lined spectroscopic binary with an orbital period of 218.0 days and a large eccentricity of 0.6. [ 30 ] [ 34 ] The Washington Double Star Catalogue lists an angular separation between the two components of 0.2 arcseconds —an angle which equates to a ...
