What is 16 Serpens
16 Serpentis lodges among the coils of the Serpent, about 231 light-years away. K-type, orange and slightly cooler than the Sun, it glows with the warm light that marks ripe giants. The kind of star a sky-hunter notices once —and then returns to seek, month after month, among the celestial reptile's folds.
