What is HIP 73100

Boötes offers another face: a yellow-white F-type star, slightly hotter than the Sun, perched 82 light-years away. Its light set out around 1944, the winter of the Normandy landings. An entire history of postwar recovery and space race fits inside the journey of these photons, delivered tonight at magnitude 5.63, right on the threshold of the human eye.
