==History==
The first important revelation about the star was in 1792 by [[Giuseppe Piazzi]],<ref>http://www.daviddarling.info/encyclopedia/A/61Cyg.html</ref> who demonstrated the star's unusually large proper motion and referred to the system as the ''Flying Star''. [[Friedrich Georg Wilhelm von Struve]] was able to measure the star as a [[binary star|binary]] in 1830. However the star did not become significant in history until 1838, when German mathematician and astronomer [[Friedrich Wilhelm Bessel]] calculated its distance using trigonometric [[parallax]], the first celestial object outside our own system to be measured in such a way.<ref>httphttps://www.britannica.com/EBchecked/topic/547165/61-Cygni</ref> The distance he calculated was so enormous, that the distance could best be adequately explained in the amount of years it took light to reach us from the binary pair.
