Planetary nomenclature, like terrestrial nomenclature, is a system of uniquely identifying features on the surface of a planet or natural satellite so that the features can be easily located, described, and discussed. Since the invention of the telescope, astronomers have given names to the surface features they have discerned, especially on the Moon and Mars. To found an authority on planetary nomenclature, the International Astronomical Union (IAU) was organized in 1919 to designate and standardize names for features on Solar System bodies.

Danilova is an impact crater on Venus. It was named in 1991 after the Russian ballet dancer Maria Danilova.
De Lalande is a multiring impact crater on Venus. It has a diameter of 21.6 km (13.4 mi) and wall width of 5.6 km (3.5 mi). The crater has an outer rim but no peak and is in close proximity to the volcano Gula Mons.
Cleopatra is an impact crater on Venus, in Maxwell Montes. Cleopatra is a double-ring impact basin about 100 kilometers (62 mi) in diameter and 2.5 kilometers (1.6 mi) deep. A steep-walled, winding channel a few kilometers wide breaks through the rough terrain surrounding the crater rim. A large amount of lava originating in Cleopatra flowed through this channel and filled valleys in Fortuna Tessera. Cleopatra is superimposed on the structures of Maxwell Montes and appears to be undeformed, indicating that Cleopatra is relatively young. The crater is named after Egyptian queen Cleopatra VII.
Tir Planitia is a large plain on the planet Mercury. The name Tir (تیر) is the Persian word for "Mercury", and the name was approved in 1976. It was first observed in detail by Mariner 10. It lies between the large crater Mozart and the ancient Tolstoj basin.
Kuiper is a moderate-size crater with a central peak cluster located at 11.35°S 31.23°W on Mercury. It is 62 kilometers in diameter and was named after Dutch-American astronomer Gerard Kuiper in 1976. It is one of only 2 Mercurian craters which are named not after artists, and one of very few cases when the same name is used for 3 craters. Gerard Kuiper, being a leader of American planetary science, died shortly before the first images of Mercurian surface were made.
Vyāsa is a crater on Mercury. It was named by the IAU in 1979, after the Indian poet Vyasa. It is Tolstojan in age.
Isabella is the second largest impact crater on Venus. The feature was named in 1994, in honor of the 15th Century queen of Spain, Isabella I of Castile. Located at 30 degrees south latitude, 204 degrees east longitude, the crater has two extensive flow-like structures extending to the south and to the southeast. The end of the southern flow partially surrounds a pre-existing 40-kilometer (25 mi) circular volcanic shield. The southeastern flow shows a complex pattern of channels and flow lobes, and is overlain at its southeastern tip by deposits from a later 20-kilometer (12 mi) diameter impact crater, Cohn.
Nanichi is a crater found the Magellian region on the planet Venus. It measures 19 km in diameter, and is located at +East, 0 - 360 using the planetocentric coordinate system.
Mariko is an impact crater on Venus. In 1997 it was named for a common female Japanese first name, in accordance with planetary nomenclature rules for Venusian craters under 20 km in diameter.
Ronald Greeley was a Regents’ Professor in the School of Earth and Space Exploration (SESE) at Arizona State University (ASU), the Director of the NASA-ASU Regional Planetary Image Facility (RPIF), and Principal Investigator of the Planetary Aeolian Laboratory at NASA-Ames Research Center. He was involved with lunar and planetary studies since 1967 and most recently focused his research on understanding planetary surface processes and geologic histories.
Mons is a mountain on a celestial body. The term is used in planetary nomenclature: it is a part of the international names of such features. It is capitalized and usually stands after the proper given name, but stands before it in the case of lunar mountains.
PateraPAT-ər-ə is an irregular crater, or a complex crater with scalloped edges on a celestial body. Paterae can have any origin, although the majority of them were created by volcanism. The term comes from Latin, where it refers to a shallow bowl used in antique cultures.
