- There are no orbital [/Apollo%20program Apollo] photographs of Hertzsprung. During each one of the Apollo missions, this area was in complete darkness (no sunlight, and... no [/Earthshine Earthshine] because Hertzsprung is a farside formation!). The antipodal region of Hertzsprung ([/Mare%20Fecunditatis Mare Fecunditatis]) was always in full sunlight, which is the reason why the antipode of Hertzsprung was one of the most frequently photographed regions on the entire moon! We could call the Hertzsprung part of the moon "Apollo's dark and unphotographed region". Research: Danny Caes
- Hertzsprung's western part is noticeable near the left margin of ZOND 6's photograph of Vavilov, see: Frame 3c. Research: Danny Caes
- Hertzsprung is also depicted in ZOND 6's Frame 4. Hertzsprung's location is a little bit below and to the left of the black cross near the curved limb. Research: Danny Caes

Description
This is a multi-ring impact basin with four rings with diameters of 150, 255, 380 and 570 km. It is a Nectarian age mascon basin with a -45 mg anomaly.
Description: Wikipedia
Additional Information
- An alternative depth of 4.5 km and a rim height of 1.06 km were given by Spudis & Adkins, 1996 (LPSC).
- Mg-suite plutons exposed on basin floor: Shearer and Neal.
Nomenclature
- The IAU crater name honors Ejnar Hertzsprung (October 8, 1873, Copenhagen – October 21, 1967, Roskilde), a Danish chemist and astronomer. In the period 1911-1913 with Henry Norris Russell, he developed the Hertzsprung-Russell diagram. In 1913 he determined the distances to several Galactic Cepheid stars by statistical parallax, and was thus able to calibrate the relationship discovered by Henrietta Leavitt between Cepheid period and luminosity. In this determination he made a mistake, possibly a slip of the pen, putting the stars 10 times too close. He used this relationship to estimate the distance to the Small Magellanic Cloud.
- The impact basin is named after the crater.
- Hertzsprung was among the long list of farside names approved by the IAU in 1970 and published in [/Menzel%2C%201971 Menzel, 1971].
- In the planning for [/Apollo%20program Apollo 8], the first manned circumlunar mission (1968), this crater (which did not then have an official name) was referred to informally as Gilruth (source: Phil Stooke's LPOD).
- The name Wien (N° 156) was proprosed for Hertzsprung D (a crater southwest of [/Michelson Michelson] in the Hertzsprung basin) on the [/Sternberg%20Lunar%20Nomenclature Complete Map of the Moon] (1967/1969) made under the direction of the [/Sternberg%20Institute Sternberg Institute]. Hertzsprung itself (or possibly just the area enclosed by the innermost ring?) was given the provisional name [/Kibal%27chich Kibal'chich]. That name was later adopted by the [/IAU IAU] for a different crater nearby. Research: Danny Caes.
- Three chain-like formations in and near the basin Hertzsprung were once called GDL ([/Catena%20Leuschner%20%28GDL%29 Catena Leuschner]), GIRD ([/Catena%20Michelson%20%28GIRD%29 Catena Michelson]), and RNII ([/Catena%20Lucretius%20%28RNII%29 Catena Lucretius]) on the [/Sternberg%20Lunar%20Nomenclature Complete Map of the Moon] (1967/1969) made under the direction of the [/Sternberg%20Institute Sternberg Institute]. These three chain-like formations are all related to the basin [/Mare%20Orientale Mare Orientale] (southeast of Hertzsprung). The southern two of the three chains (GIRD and RNII) are depicted and named on this part of the above mentioned map (at location K-6). Research: Danny Caes
The Hertzberg basin?
Only the book The Farside of the Moon; a Photographic Guide from Charles J. Byrne (Springer 2008) knows a certain basin on the farside of the moon called the "Hertzberg Basin". See page 147 of that book.- DannyCaes DannyCaes Dec 9, 2017
