What is HIP 42172
Barely eighty-two light years separate this yellow-white F-type from the observer, in the small zodiacal constellation of Cancer. Its current light left the star around 1944, in the midst of the Normandy landings and the closing chapters of the Second World War. A close neighbour in galactic terms, slightly hotter than the Sun and evolving along the same lines as other nearby, well-studied stars.
