The Clock

Abbreviation:	Hor
Genitive:	Horologii
Origin:	Nicolas Louis de Lacaille, 1756
Fully Visible:	90°S – 22°N

French astronomer Nicolas Louis de Lacaille (1713–1762) travelled to South Africa in the mid-eighteenth century where he constructed an observatory and spent two years observing the southern skies. Not only did he catalogue nearly 10,000 southern stars, he also surveyed 42 'nebulous' objects and devised over a dozen new constellations. Originally named l'Horloge, this faint southern hemisphere constellation was later Latinised to Horologium.

Other Interesting Stars
GJ 1061		This high proper motion star is far too faint to be seen by the naked eye. The main reason for its apparent speediness is its closeness to Earth. It is a tiny, red dwarf star, barely ten percent the mass of the Sun
Deep Sky Objects
C87		This is a globular cluster, visible only with optical aids. It was discovered in 1826 and is also catalogued as NGC 1261.
