  • Depth data from Kurt Fisher database
    • Westfall, 2000: 3.12 km

  • Named for (John) Thomas Romney Robinson (1792-1882), Irish astronomer, physicist, and meteorologist long associated with the Armagh Astronomical Observatory.
  • Robinson was proposed by W. R. Birt as a name for the elevated tableland between the craters now known as J. Herschel and South: "It is proposed to designate this table-land "Robinson," in honour of the Astronomer of Armagh." (Birt, 1863, p. 10). The following thumbnail links to a simulation of the elevated feature Birt describes observing from London on 1862 Mar 12 at around 20:00 UT (08:00 GMAT):

  • In Neison, 1876, the name was redefined to designate a crater (listed as Horrebow A in Beer and Mädler) in the central part of the tableland: "The name Robinson was originally applied to the whole tableland, but as this is scarcely a true formation and is of very indefinite character, it has been restricted to the principal and conspicuous ring-plain near the centre, with considerable advantage and without introducing sensibly any confusion." (page 256)
  • Horrebow A was noted as Catalog number 1684 in Mary Blagg's Collated List, and adopted with Neison's proposed name in the original IAU nomenclature of Named Lunar Formations. The name remains attributed, there, to Birt.
  • Related material on other features named after Irish scientists.
  • It would be interesting to know the biography of a certain J. Hedley Robinson, the author of the book Using The Telescope; a handbook for astronomers. His name is mentioned in the article The Origin of the Cytherean Cusp Caps by C.M.Pither (Journal of the British Astronomical Association, 1963). See page 90 in Mysterious Universe, a handbook of astronomical anomalies (William R. Corliss, The Sourcebook Project, 1979). - DannyCaes Mar 30, 2015
