Description: Elger

(IAU Directions) CONDORCET.--A very prominent ring-plain, 45 miles in diameter, situated on the mountainous S.E. margin of the Mare Crisium. It is encircled by a lofty wall about 8,000 feet in height. The dark interior of this and of the three preceding formations render them easily traceable under a high angle of illumination.

  • Satellite crater Condorcet T is on the ALPO list of bright ray craters.
  • Condorcet T and adjacent Condorcet TA were captured on Apollo 16's panoramic ITEK-camera frame AS16-P-9182 (scroll rightward until you see a couple of bright craters with dark streaks on their inner slopes)(the one with the "central peak" on its floor is Condorcet T, the other one with the long dark streak is Condorcet TA).- DannyCaes May 7, 2011
  • Condorcet T is also a thermal anomaly crater, implying a youthful age - Moore et al, 1980


Marie Jean Antoine Nicolas Caritat, Marquis de Condorcet (September 17, 1743 – March 28, 1794) was a French philosopher, mathematician, and early political scientist.

Nic Parthenius?

The crater now known as Condorcet could have been Melchior a Briga's Nic Parthenius (see the location of the capital omega (Nic Parthenius) on Melchior a Briga's map of 1747; pages 90-91 in E.A.Whitaker's Mapping and Naming the Moon). - DannyCaes Feb 20, 2016
