What is HIP 109654
On the flank of the winged horse, in Pegasus, beats an orange type-K star whose light set out 258 years ago, when the French encyclopaedists were mapping human knowledge. Cooler and calmer than the Sun, its surface barely reaches four thousand degrees, yet its swollen size lets it shine generously. It is an aged star in an advanced stage of life, its coppery hue recalling amber kept in old wood. In the northern autumn sky its warm tone stands out among the cold white of its neighbours.
