Delta Horologium
What is Delta Horologium
δ Horologii shines white and serene at 179 light-years, set within the small southern constellation of the Clock that Lacaille named in tribute to the pendulum clocks of his age. An A-class star, hotter and whiter than the Sun, still young, it glows with the clean light only stars of fresh hydrogen can give off. A discreet flame within a constellation almost no one knows how to name.
