What is 66 Aquarii

66 Aquarii burns 433 light-years away, an orange giant swollen to roughly thirty-seven times the Sun's radius. Its light, four hundred times more intense than the Sun's, set out when Galileo first pointed his glass to the stars. It is listed among suspected variables as NSV 14291: it pulses faintly, almost imperceptibly, like so many mature giants of the Aquarian sky.
