Description


Description: Elger

(IAU Directions) RITTER.--Is very similar in every respect to Sabine. A curved rill mentioned by Neison is on the N.W. side of the floor and is concentric with the wall. On the N. side of this ring-plain are three conspicuous craters, the two nearer being equal in size and the third much smaller.

  • There's a very small crater between the two bowl-shaped craters Ritter B and C (immediately north-northwest of Ritter). This small crater is an interesting test object for observers of the moon with powerful telescopes. Research: Antoine Van Der Jeugt and Danny Caes.

Nomenclature

  • The present IAU name honors two men:
    • Karl Ritter (August 7, 1779 – September 28, 1859), a German geographer.
    • Georg August Dietrich Ritter (December 11, 1826 – February 26, 1908), a German astrophysicist. He was a professor at RWTH Achen University.
  • The name Ritter (honoring Karl) was part of the original IAU nomenclature of Blagg and Müller (catalog number 542), where the name is attributed to Beer and Mädler.
  • Georg was added as a second honoree in Menzel, 1971, where little was known about him other than that he had written some paper in the 1880's.
  • According to Neison (1880), the British Association Lunar Committee (Birt?) at one time advocated changing the name Ritter B to J. Gwilt and Ritter C to G. Gwilt, possibly honoring English architect Joseph Gwilt and his son George Gwilt. Their suggestions were not adopted in later catalogues.
