| Description | The Pendulum Clock was named by Lacaille to honor Christiaan Huygens, the Dutch scientist who invented the pendulum clock in 1656, revolutionizing accurate timekeeping and navigation. It sits in a faint area of the southern sky between Eridanus and the bright star Achernar. Despite its obscurity, it contains the Horologium Supercluster — one of the largest known structures in the observable universe, a vast concentration of galaxy clusters stretching roughly 550 million light-years across and about 700 million light-years from Earth. The brightest star, Alpha Horologii, is an orange giant about 115 light-years away. |
