Mensa

From Slackerpedia Galactica

Named for the ancient Greek Roman god of IQ test takers, Mensa is yet another recently-invented southern constellation, created by the French astronomer Nicolas Louis de Lacaille in the mid-1700's. It is notable as being the worst of the long list of astronomical non-constellations, its brightest star barely reaches naked eye visibility at magnitude 5 or so. It's also faintly notable for having a smidgen of the LMC within its borders.
