What is 11 Pegasi
11 Pegasi is a white A-type star kindled some 569 light-years away, along the western flank of the Winged Horse. Hotter and more luminous than the Sun, it pours out the clean, bluish light that betrays young hydrogen suns. The light crossing the eyepiece tonight set out toward the mid-fifteenth century —the years when Europe was rediscovering the geographers of antiquity— and only now completes the path to the constellations of northern autumn.
