Additional Information
Nomenclature
- Named for Johann Christian Doppler (November 29, 1803 – March 17, 1853), an Austrian mathematician and physicist, most famous for the hypothesis of what is now known as the Doppler effect which is the apparent change in frequency and wavelength of a wave that is perceived by an observer moving relative to the source of the waves.
- Doppler was among the long list of farside names approved by the IAU in 1970 and published in Menzel, 1971.
- In the planning for Apollo 8, the first manned circumlunar mission (1968), this crater (which did not then have an official name) was referred to informally as "Von Braun", a name that is currently used to refer to a completely different nearside crater (source: Phil Stooke's LPOD).
