What is HIP 18723
In Eridanus, the long celestial river, glows a white A-type star about 351 light-years away. Its light began its voyage around 1675, while the Royal Observatory at Greenwich was being founded and astronomy was learning to measure the sky more sharply. Hotter than the Sun, its white light threads the night like a strand of silver.
