Its story

39 Cygni rests along the wing-arm of the Swan, the long cross that rides the summer Milky Way. It is an orange K-type giant —cool, eye-friendly, the colour of glowing copper— sitting some 250 light-years away. Its light set out in the early 1700s, while Flamsteed was still revising his catalogues, and arrives now with the patient hue of embers that refuse to fade.
