More about selenography
Selenography “the branch of astronomy that charts the moon’s surface” is a compound of seleno- and -graphy. The former comes from Ancient Greek selḗnē “moon,” while the latter ultimately comes from Ancient Greek graphḗ “writing.” The noun selḗnē is also the source of Selene, the moon goddess, and comes from sélas “shine,” plus the noun-forming suffix -nē, making selḗnē literally mean “shinier, lighter.” A similar formation appears in Latin with lūna “moon,” contracted from the root luc- “light” and the suffix -na. Take care not to confuse Selene with the name Celine, from either Latin Caelina (from caelum “heaven”) or French Marceline (from Latin Marcus). Selenography was first recorded in English in the 1640s.
