Which constellation in the southern sky has the same name as an organization containing many intelligent people?

The constellation Mensa, visible in the southern celestial hemisphere, shares its name with a renowned organization for individuals of high intelligence. This celestial "Table Mountain" was charted by French astronomer Nicolas Louis de Lacaille in the 18th century. He named it in honor of Table Mountain in South Africa, a prominent flat-topped landmark overlooking Cape Town, where he conducted his astronomical observations. The constellation itself is quite faint, with no particularly bright stars, and contains part of the Large Magellanic Cloud, which Lacaille thought resembled the "tablecloth" of clouds often seen over the real Table Mountain.

The organization Mensa, on the other hand, is the largest and oldest high-IQ society in the world. Founded in Oxford, England, in 1946 by Roland Berrill and Lancelot Ware, its primary aim is to identify and foster human intelligence for the benefit of humanity. Membership is open to individuals who score in the 98th percentile or higher on a standardized, supervised intelligence test.

The name "Mensa" was deliberately chosen for the society because it means "table" in Latin, symbolizing a round-table where members of diverse backgrounds can gather as equals, regardless of race, religion, or social standing. This shared Latin root creates an intriguing link between a dim constellation commemorating a geographical feature and a global society celebrating exceptional intellect, both united by the simple, yet profound, concept of a table.
