What is 20 Pegasi

20 Pegasi is a yellow-white F-type sun, 252 light-years away, on the flank of the Winged Horse. Hotter and more luminous than our own, it sits in that middle band between the Sun and the great bluish-white stars. Its light set out when the Ottoman Empire was still a European power and the independence of the United States was barely a decade old. Pegasus, with its Square, is a perfect backdrop for this pearly-toned lantern.
