Interesting story on this one. 61 Cygni is a double star orbiting each other at a rate of 659 years. It is the fourth-closest star visible to the unaided eye from our planet after Alpha Centauri, Sirius, and Epsilon Eridani at only 11.4 light years.

However, most importantly it has one of the largest proper motions – that is, sideways motion along our line of sight – of any star in our sky. This motion was first noticed by Giuseppe Piazzi in 1805.

Although it’s not bright, it moves exceptionally rapid against the background of more distant stars. It's large proper motion has given 61 Cygni the nickname "The Flying Star." The fast motion of the binary indicated that it was relatively close to Earth. That fact prompted German astronomer F. W. Bessel to use 61 Cygni as the first star to have its distance measured by observation. As a result it is sometimes called “Bessel’s Star.”

Also this star is so fast it seems to have outrun the astrobin plate-solving software.
