Zet

Its story

Zeta Horologii shines with a yellow-white light in the Clock, a small southern constellation traced by Lacaille in the eighteenth century as a tribute to the scientific instruments of his time. It is an F-type star 160 light-years away, slightly hotter than the Sun, nearly anonymous to the unaided eye yet essential for anyone exploring this corner of the southern sky. Its existence is a reminder that the firmament, far from being fixed by ancient myth, remains a map each generation rewrites with its own tools.
