Description
Description: Elger
(IAU Directions) SIMPELIUS.--Another grand circumvallation, almost as large as Pentland, but unfortunately much foreshortened. One of its peaks on the W. rises to a height of more than 12,000 feet above the floor, on which there is a small central mountain. Between Simpelius and Pentland are several ring- plains, most of which appear to have been squeezed and deformed into abnormal shapes.

Additional Information
- Depth data from Kurt Fisher database
- Westfall, 2000: 5.78 km
- Cherrington, 1969: 3.29 km
- According to LTVT, the longest shadows (from the prominence on the east rim in LO-IV-094H) correspond to height differences of 5,300 m. - Jim Mosher
- Simpelius J and the small crater on rim of Simpelius B are radar bright at 70 cm.
- The bowl-shaped high albedo craters Simpelius J and Schomberger G (at approximately 76°S/ 8°E) are interesting targets during Full Moon, because they act like "pointers" to the approximate location of the Moon's South Pole. - DannyCaes Sep 18, 2010
- Schomberger G is called "Simpelius G" on LAC 137 (page 275) of the Clementine Atlas. - DannyCaes Oct 12, 2012
Nomenclature
- Named for Hugh Sempill (or Semple) (in Latin, Hugo Simpelius or Sempilius) (lived from between 1589 and 1596 to 1654), a Scottish Jesuit mathematician and linguist. He served as procurator of the Royal Scots College in Madrid (now located in Salamanca).
- Crater Simpelius D was called Einstein by Hugh Percy Wilkins and Patrick Moore, but the IAU decided to use that name for a crater on the moon's west-northwestern limb. According to Wilkins and Moore's book, Einstein was a great scientist (1879-1955). - DannyCaes
