{{main|Planetary nomenclature}}

In addition to naming planets and satellites themselves, the individual [[Lists of geological features of the Solar System|geological and geographical features]] such as craters, mountains, and volcanoes, on those planets and satellites also need to be named.

In the early days, only a very limited number of features could be seen on other Solar System bodies other than the [[Moon]]. Craters on the [[Moon]] could be observed with even some of the earliest telescopes, and 19th-century telescopes could make out some features on Mars. Jupiter had its famous [[Great Red Spot]], also visible through early telescopes.

In 1919, the IAU was formed, and it appointed a committee to regularize the chaotic lunar and Martian nomenclatures then current. Much of the work was done by [[Mary Adela Blagg]], and the report ''Named Lunar Formations'' by Blagg and Muller (1935), was the first systematic listing of lunar nomenclature. Later, "The System of Lunar Craters, quadrants I, II, III, IV" was published, under the direction of [[Gerard P. Kuiper]]. These works were adopted by the IAU and became the recognized sources for lunar nomenclature.

The Martian nomenclature was clarified in 1958, when a committee of the IAU recommended for adoption the names of 128 [[albedo feature]]s (bright, dark, or colored) observed through ground-based telescopes (IAU, 1960). These names were based on a system of nomenclature developed in the late 19th century by the Italian astronomer [[Giovanni V. Schiaparelli]] (1879) and expanded in the early 20th century by [[Eugene M. Antoniadi]] (1929), a Greek-born astronomer working at [[Meudon]], France.

However, the age of [[space probe]]s brought high-resolution images of various Solar System bodies, and it became necessary to propose naming standards for the features seen on them.
