Gateway to Astronaut Photography of Earth

Planetary nomenclature, like terrestrial nomenclature, is used to uniquely identify a feature on the surface of a planet or satellite so that the feature can be easily located, described, and discussed. This gazetteer contains detailed information about all names of topographic and albedo features on planets and satellites (and some planetary ring and ring-gap systems) that the International Astronomical Union (IAU) has named and approved from its founding in 1919 through the present time.

行星命名学，如同地球命名学，旨在为行星或卫星表面的特征提供唯一标识，以便于其定位、描述和讨论。本地名录详尽地记录了自国际天文学联合会（IAU）自1919年成立以来至现今，对行星、卫星（以及部分行星环与环隙系统）上的地形和反照率特征所命名的所有名称及其批准信息。
