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.
Pleiades image of Central Park in New York City. Pléiades constellation is composed of two very-high-resolution (50 centimeters pan & 2.1 meter spectral) optical Earth-imaging satellites. Pléiades-HR 1A and Pléiades-HR 1B provide the coverage of Earth's surface with a repeat cycle of 26 days.
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
16 Tauri is a blue-white B-type subgiant with an apparent magnitude of +5.45. It is approximately 430 light years from the Sun; [5] about the same distance as the Pleiades. The interstellar extinction of this star is fairly small at 0.05 magnitudes. [11]

The Golden Gate of the Ecliptic is an asterism in the constellation Taurus that has been known
The asterism was recognized as the constellation ASH.IKU "The Field" on the MUL.APIN cuneiform tablets from about 1100 to 700 BC. [13] Alpheratz is now only considered a part of the constellation Andromeda whereas formerly the star was a part of both constellations. The Bowl of Virgo is formed by the stars Beta, Gamma, Delta, Epsilon and Eta ...
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.
