Flamsteed designation

Flamsteed designation is a system used to name stars based on their position within a constellation. Developed by British astronomer John Flamsteed in the late 17th century, each star in a constellation is assigned a number, typically in order of brightness, followed by the Latin name of the constellation. For example, "61 Cygni" indicates it is the 61st star observed in the constellation Cygnus. This method allows astronomers to systematically identify and reference stars within the vast night sky, facilitating easier communication and study of these celestial bodies.
