Mensa (Latin for "table") is a constellation in the southern celestial
hemisphere near the south celestial pole. It is one of the 88 modern
constellations, and one of twelve drawn up in the 18th century by
French astronomer Nicolas-Louis de Lacaille. Originally named for Table
Mountain overlooking Cape Town, South Africa, where Lacaille made
observations, it covers a keystone-shaped wedge of sky of approximately
153.5 square degrees. Other than the south polar constellation of
Octans, it is the most southerly of constellations and is only
observable south of the 5th parallel of the Northern Hemisphere. Barely
visible in suburban skies, Mensa is one of the faintest constellations
in the night sky. At least three of its star systems have been found to
have exoplanets. Parts of the Large Magellanic Cloud, several star
clusters and a quasar lie in the area covered by the constellation.
