- Horologium (Latin hōrologium, the pendulum clock, from Greek ὡρολόγιον, lit. ‘an instrument for telling the hour’) is a constellation of six stars faintly visible in the southern celestial hemisphere. It was first described by the French astronomer Nicolas-Louis de Lacaille in 1756 and visualized by him as a clock with a pendulum and a second hand. In 1922 the constellation was redefined by the International Astronomical Union (IAU) as a region of the celestial sphere containing Lacaille’s stars, and has since been an IAU designated constellation. Horologium’s associated region is wholly visible to observers south of 23°N.

A lion cub accompanying Leo, introduced by the Polish astronomer Johannes Hevelius in his star catalogue of 1687 and depicted in his star atlas published posthumously in 1690. He formed it from 18 faint stars between Ursa Major and Leo where the short-lived constellation Jordanus once flowed. The brightest stars of Leo Minor are of only fourth magnitude and there are no legends associated with it.
