Abbreviation:Men
Genitive:Mensae
Origin:Nicolas Louis de Lacaille, 1756
Fully Visible:90°S – 5°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 Montagne de la Table, this faint southern hemisphere constellation was later Latinised to Mons Mensae and eventually shortened to just Mensa. It commemorates Table Mountain near the modern city of Cape Town and is the only constellation named after a geographical feature on the Earth. Part of the Large Magellanic Cloud spills over into this constellation from Dorado.
