61 Cygni

Definition and stakes

Portrait of Robert S. Ball Robert S. Ball,  The Story of the Heavens

“ Fig. 94.—61 Cygni and the Comparison Stars.
The case of 61 Cygni is, however, exceptional. It is one of our nearest neighbours in the heavens. We can never find its distance accurately to one or two billions of miles; but still we have a consciousness that an uncertainty amounting to twenty billions is too large a percentage of the whole. [Pg 448] We shall presently show that we believe Struve was right, yet it does not necessarily follow that Bessel was wrong. The apparent paradox can be easily explained.

Portrait of William Tyler Olcott William Tyler Olcott,  Star Lore Of All Ages — Cygnus… (1911)

“ Between α, γ, and ε Cygni is one of the vacant spaces in the Milky Way, a black and seemingly bottomless abyss, the brink over which man peers into the profound and mysterious depths of interstellar space. This wonderful region in the sky is known as "the Northern Coal Sack."
Cygnus is celebrated as containing the nearest lucid star in the northern hemisphere, a 5.6 magnitude star, barely visible to the naked eye, known as "61 Cygni." It is a double star, both being golden yellow in colour, situated six degrees north and east of the star ε Cygni.

Portrait of E. W. Bullinger E. W. Bullinger,  The Witness of the Stars

“ In the Denderah Zodiac it is named Tes-ark, which means this from afar.
Plate 20: CYGNUS (the Swan) It is a most brilliant and gorgeous asterism of 81 stars; one of the 1st or 2nd, six of the 3rd, twelve of the 4th magnitude, etc. It contains variable stars, five double stars, and one quadruple. The star marked “61 Cygni” is known as one of the most wonderful in the whole heavens. It consists of two stars which revolve about each other, and yet have a progressive motion common to each!
