Selenography: The study of the surface and physical features of the Moon. Historically, the principal concern of selenographists was the mapping and naming of the lunar maria, craters, mountain ranges, and other various features. This task was largely finished when high resolution images of the near and far sides of the Moon were obtained by orbiting spacecraft during the early space era. Nevertheless, some regions of the Moon remain poorly imaged (especially near the poles) and the exact locations of many features are uncertain by several kilometers. Today, selenograhy is considered to be a subdiscipline of selenology, which itself is most often referred to as just “lunar science.” The word selenography is derived from the Greek lunar deity Selene-ography (to write).
