Its story

11 Serpentis shines in the Serpent's Head, one of the two halves into which this constellation was split by Ophiuchus. It is an orange K-type giant whose mild light takes 280 years to cross the space between us —it set out when Newton was publishing his Principia. Today it reaches the trained eye at magnitude 5.5, almost at the threshold of visibility under rural skies.
