What is HIP 81754

In Ophiuchus, the Serpent Bearer, shines a yellow-white star of type F, slightly livelier than the Sun. Its light has been travelling for only 137 years: it left in 1888, as Heinrich Hertz proved in his laboratory the existence of radio waves. A small, almost familiar flame, lost among the coils of a mythological serpent-handler.
