Planetary Nomenclature
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. IAU approval procedure When images are first obtained of the surface of a planet or satellite, a theme for naming features is chosen and a few important features are named, usually by members of the appropriate IAU task group (a commonly accepted planet-naming group). Later, as higher resolution images and maps become available, additional features are named at the request of investigators mapping or describing specific surfaces, fe ...

International Astronomical Union
The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded on 28 July 1919 in Brussels, Belgium and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. the Union had 85 national members and 12,734 individual members, spanning 90 countries and territories. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ...

Aphrodite Terra
Aphrodite Terra is one of the three continental regions on the planet Venus, the others being Ishtar Terra and Lada Terra. It is named for Aphrodite, the Greek equivalent of the goddess Venus, and is found near the equator of the planet. Aphrodite Terra is about half the size of Africa, making it the largest of the terrae. Description Aphrodite Terra was named by the International Astronomical Union, the governing body for planetary and satellite nomenclature, after Aphrodite, the goddess of love. The name was chosen because Aphrodite is the Greek equivalent of the Roman goddess Venus. Located near the equator of Venus, Aphrodite Terra has an area about half the size of Africa Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surfac ..., and is much larger than the rougher Ishtar Terra ...

Ishtar Terra
Ishtar Terra is the second largest of the three continental terrae regions on the planet Venus, the others being Aphrodite Terra and Lada Terra. It is a highland region named after the Akkadian goddess Ishtar, and is found in the north of the planet. Note that Ishtar Terra is located near the negative pole if Venus's rotation is defined as prograde by the right-hand rule. The rotation of the planet is commonly characterized as retrograde in order to correlate its northern hemisphere with Earth's, in which case Ishtar Terra is near the north pole. This is the convention normally used for maps. In size, it is roughly between Australia and the contiguous United States, making it the second-largest of the terrae. On its eastern edge lies the great mountain chain Maxwell Montes, which is about high, compared to Mount Everest at . On one side of the mountain chain is the impact crater Cleopatra, in diameter filled with lava. Ishtar Terra contains the four main mountain rang ...

Lada Terra
Lada Terra, named for a Lada (mythology), Slavic goddess of Love, is a major landmass near the south pole of Venus which is centered at 60°S and 20°E and has a diameter of . It is defined by the International Astronomical Union as one of the three "major landmasses," or planetary nomenclature#terra, terrae, of Venus. The term "landmass" is not analogous to the landmass on Earth, as there are no apparent oceans on Venus. The term here applies to a substantial portion of land that lies above the average planetary radius, and corresponds to highlands. The broad region of Lada Terra contains massive corona (planetary geology), coronae, rift zones, and volcanic plains as well as many other features that scientists use to attempt to piece together the history of this complex planet. The distinctive cross-cutting relationships found in the bedding of Lada Terra have been important in realizing relative ages of the extensional belts and coronae, as well as the complex Tessera (Venus), tes ...

Maxwell Montes
Maxwell Montes is a mountain range on the planet Venus, of which Skadi Mons is the List of tallest mountains in the Solar System, highest. General description Located on Ishtar Terra, the more northern of the planet's two major highlands, Maxwell Montes is high. It rises about 6.4 kilometers above and to the east (21,000 ft above, and 4 miles (6.44 km) to the east) of Lakshmi Planum, and is about long by wide. The western slopes are very steep, whereas the eastern slopes descend gradually into Fortuna Tessera. Due to its elevation, it is at its top the coolest (about ) and least pressurised (about ) location on the surface of Venus. Origins and geology The origin of the Lakshmi Planum and the mountain belts such as Maxwell Montes is controversial. One theory suggests they formed over a hot plume of material rising from Venus's interior, while another says the region is being compressed (pushed together) from all sides, resulting in material descending into the plane ...

Lada And Lado
Lada and Lado are alleged Slavic deities. Lada was first mentioned around 1405–1412 in the sermons of Lucas of Wielki Koźmin, which warned against worshipping Lada and other gods during spring ceremonies and folk performances. The deities owe their popularity to Polish priest Jan Długosz, who described Lada as a goddess and a god of war in his works and compared her to the Roman Mars, to Aleksandr Faminstyn, who recognized the name ''Lada'' in Russian songs as attributed to the goddess of marriage, and to scholar Boris Rybakov, who insisted on recognizing her historicity. However, the vast majority of religious scholars and Slavists reject the historicity of these deities, believing that they owe their divine status to a misunderstanding of the song refrains by medieval scribes. According to some scholars of Baltic mythology, Lada was also worshipped by the Balts, but this view is also considered controversial. Planetoid (2832) Lada was named after her. Sources ...

Surface Features Of Venus
The surface of Venus is dominated by geologic features that include volcanoes, large impact craters, and aeolian erosion and sedimentation landforms. Venus has a topography reflecting its single, strong crustal plate, with a unimodal elevation distribution (over 90% of the surface lies within an elevation of -1.0 and 2.5 km) that preserves geologic structures for long periods of time. Studies of the Venusian surface are based on imaging, radar, and altimetry data collected from several exploratory space probes, particularly '' Magellan'', since 1961 (see Venus Exploration). Despite its similarities to Earth in size, mass, density, and possibly composition, Venus has a unique geology that is unlike Earth's. Although much older than Earth's, the surface of Venus is relatively young compared to other terrestrial planets (<500 million years old), possibly due to a global-scale resurfacing event that buried much of the previous rock record.
