In a heavily cratered area of the northern hemisphere of the farside, Quetelet is an older crater, with a smooth rim pocked with a number of later craters. Most of the floor is covered by a smooth material that almost covers the crater's peak. A rough deposit -from an old rim slump? - covers the eastern third of the floor.

  • Quetelet is the only one of the lunar surface formations in the list of the IAU's Q-names (with Quetelet T of course...).
  • Named for Lambert Adolphe Jacques Quételet (February 22, 1796 – February 17, 1874), a Flemish astronomer, mathematician, statistician and sociologist. He founded and directed the Brussels Observatory.
  • IAU spelling changed from Quételet to Quetelet on March 22, 2010.
  • In the Flemish city Ghent (the birthplace of L.A.J.Quetelet) the street named after Quetelet (Queteletstraat) is located between the Tolpoort and the Van Crombruggestraat. It is located north of the centre of Ghent.- DannyCaes Mar 28, 2010
  • L.A.J.Quételet seems to have been the discoverer of the optical phenomenon known as Quételet Rings, a multicolored effect which could be observed on a somewhat dirty mirror or glass-window, when a bright pointlike lightsource (a small lightbulb) is held between the observing eye and the mirror/ glass-window. - DannyCaes Dec 12, 2010
