HIP 11840
What is HIP 11840
At 271 light-years, in the modest northern Triangle, blazes an orange giant whose light set out in the late eighteenth century, when William Herschel discovered Uranus and doubled the known size of the solar system. Cooler and larger than the Sun, its amber tone marks a mature star. It inhabits a small, almost minimalist constellation, drawn by three modest stars in the autumn sky.
