Its story

In Circinus, the tiny compass constellation introduced by Lacaille in the eighteenth century, it shines with the orange light of class K stars. Its glow took 728 years to reach us: when it set out, books had been printed with movable type for centuries in China and in Europe the first mechanical clocks were beginning to mark time in church towers. It is a calm star, cooler than the Sun, faithful to its warm tone over time.
