Additional Information


Pettit and Nicholson

Here's the reason why a "twin"-couple of pronounced craters in Mare Orientale's Rook Mountains were called Pettit and Nicholson:
  • In the early 1920s, Edison Pettit and Seth Nicholson made the first systematic infrared observations of celestial objects. They used a vacuum thermocouple to measure the infrared radiation and thus the temperature of the Moon which led to the theory that the Moon was covered with a thin layer of dust acting as an insulator, and also of the planets, sunspots and stars. Their temperatures measurements of nearby giant stars led to some of the first determinations of stellar diameters.


Nomenclature

  • Edison Pettit (1889-1962); American astronomer active at Mount Wilson Observatory. Pettit had wide-ranging interests, and in lunar work was noted for his studies of the variation of temperatures on the lunar surface, particularly during eclipses. Wilkins and Moore also attribute a relief map of the Moon, constructed at Mount Wilson in 1930, to Pettit (their Appendix II).
  • This crater is not to be confused, thank you, IAU, with Petit
