What is Phi Serpens

Phi Serpentis is an orange star at 241 light-years, set on one of the great coils of the Serpent that the celestial Ophiuchus holds firmly in his hands. Its warm light, characteristic of K-type stars, points to a surface cooler than the Sun's and a somewhat advanced nuclear history. A quiet flame coiled around the only constellation mythology ever split into two distinct halves.
