About Mensa

Mensa is a small constellation which lies close to the south celestial pole.
The name ‘Mensa’ means ‘table’ and refers to Table Mountain...
It is the only constellation to be named after a real geographic feature on Earth, and was created by Nicolas Louis de Lacaille in 1756. He chose the name because Table Mountain overlooked his observing site when he was charting the southern sky.
