What is 27 Hydrae

27 Hydrae is a yellow-white F-type sun, 222 light-years along the long winding body of Hydra. Hotter and more luminous than our own Sun, it shines with a pearly, almost metallic tone next to the red giants peppering the monster's tail. Its light reaches us from the late eighteenth century, dispatched while Europe debated the first written constitution of the modern world. It still travels, indifferent to our dates.
