What is 47 Aquarii

47 Aquarii rests among the waters of the celestial water-bearer, a K-type orange giant cooler than the Sun yet far vaster. Its light has been travelling for 171 years — the same interval that separates the first steam locomotive from the first colour images returned from another planet. Magnitude 5.12: serene, removed, the colour of ancient amber.
