The study of the moon's geography is called selenography. Scientists who specialize in selenography are interested in mapping the surface of the moon, including its craters and mountains.
The word selenography dates to the 1640s, a time when we knew much less about our planet's only natural satellite. The word comes from the Greek selēnē, which means "moon" and is also the name of the ancient Greek moon goddess. Selenography originally focused on making maps of the moon using telescopes. Thanks to orbiting spacecraft, we now have crystal clear images of its near and far sides, and only details of areas near the moon's poles remain unmapped by selenographers.
