Its story

37 Draconis is an orange K-type giant 276 light-years away, in the long meandering of the Dragon that coils round the northern celestial pole. K giants like this one have already left the calm of the main sequence and swollen toward stellar maturity, pouring out a warm reddish glow. Its light began the voyage at the start of the eighteenth century, when Newton was still alive and calculus was taking its first steps.
