Cool red star

Its story

77 Pegasi is a red M-type giant burning at 619 light-years inside the great square of Pegasus, the winged horse of the autumn sky. Its temperate surface, barely three thousand degrees, radiates the ruddy hue typical of stars that have exhausted hydrogen and swollen to colossal sizes. The light reaching us tonight departed as Cervantes was beginning to shape Don Quixote.
