Description: Elger

(IAU Directions) POISSON.--An irregular formation on the E. of Aliacensis, extending about 50 miles from E. to W., but much less in a meridional direction. Its N. limits are marked by a number of overlapping ring-plains and craters, and it is much broken elsewhere by smaller depressions. The W. wall is about 7,000 feet in height.

  • Siméon-Denis Poisson (June 21, 1781 – April 25, 1840), was a French mathematician, geometer, and physicist. It was in the application of mathematics to physical subjects that his greatest services to science were performed. Perhaps the most original, and certainly the most permanent in their influence, were his memoirs on the theory of electricity and magnetism, which virtually created a new branch of mathematical physics.
  • Poisson Alpha (mountain-like elevation south of Poisson A) (see page 138 in Tony Dethier's Maanmonografieen).
