The [[Moon]] has numerous named [[Plain|plains]] on its surface made of dark-appearing [[basaltic rock]]s. The plains are visibly prominent on the [[near side of the Moon]] because of their contrasting appearance from the surrounding [[lunar highlands]], which are made up of [[anorthosite]], an [[igneous rock]] containing significant concentrations of highly reflective [[plagioclase feldspar]] minerals. As with other [[Selenography|topographical features on the Moon]], the official [[Planetary nomenclature|nomenclature]] for lunar plains uses a [[Latin]] naming system. Due to their darker appearance, differing elevation from the highlands, and visual prominence, noted [[Ancient Greek astronomy|ancient Greek astronomers]] such as [[Plutarch]] believed the plains were water; subsequent astronomers such as [[Galileo Galilei]] and [[Michael van Langren]] built on this belief, using Latin words for water bodies in classifying them. The Latin classifications for lunar plains are oceanus ({{literal translation|ocean}}), mare ({{literal translation|sea}}), lacus ({{literal translation|lake}}), palus ({{literal translation|marsh}}), and sinus ({{literal translation|bay}}). The largest plain is [[Oceanus Procellarum]] (''{{translation|Ocean of Storms}}''), covering much of the western half of the Moon's near side and the only plain to be classified as an oceanus. Most other prominent plains on the near side are the [[Lunar mare|lunar maria]], while the Moon's lacūs, sinūs, and paludes{{efn|The [[Latin plurals]] of mare, lacus, palus, and sinus are maria, lacūs, paludes, and sinūs, respectively.<ref>{{Cite web |title=Target: The Moon |url=https://planetarynames.wr.usgs.gov/Page/MOON/target |access-date=13 September 2025 |website=Gazetteer of Planetary Nomenclature |publisher=[[USGS Astrogeology Research Program]] |language=en}}</ref> In English, some sources also use lacus and sinus (without the [[Macron (diacritic)|Latin diacritics]]) as [[English_plurals#Nouns_with_identical_singular_and_plural|both the singular and plural]].}} are generally smaller and less visually prominent.

The classification of and other designations for lunar geographic features are determined by the [[International Astronomical Union]] (IAU)—the official international organization for the standardization of astronomy.{{citation needed|date=September 2025}}
<!--Due to ______, the majority of the Moon's plains are concentrated on the near side, with there only being a few on the far side.

==Geology==

In its [[Origin_of_the_Moon#Formation|early stages of formation]], the Moon's surface was largely molten, with its [[Lunar magma ocean|deep ocean of magma]] persisting for roughly tens of millions to hundreds of millions of years.<ref>{{Cite web |last1=Vogel |first1=Tracy |editor-last1=Saxena |editor-first1=Prabal |editor-last2=Valencia |editor-first2=Sarah |editor-last3=Bottke |editor-first3=Bill |editor-link3=Bill Bottke |title=Moon Formation |url=https://science.nasa.gov/moon/formation/ |access-date=19 September 2025 |website=[[NASA]] |language=en |quote=[T]he Moon had been molten during its formation and was covered with a deep ocean of magma for tens of millions to hundreds of millions of years...}}</ref> After the cooling of the magma at the end of this period, minerals began to [[crystallize]] and [[Planetary differentiation|differentiate]], with heavier minerals sinking into the [[Internal structure of the Moon|Moon's inner layers]] while the lighter, highly-reflective mineral of [[plagioclase feldspar]] rose to the surface and fused with other light, [[mafic]]-type crystals to form [[anorthosite]] rocks. The anorthosite accumulated to become an early stage of the Moon's outer crust. This early outer crust later [[Late Heavy Bombardment|became heavily bombarded]] by immense numbers of [[Meteoroid|meteoroids]] and other solar system debris around 4 billion years ago, with substantial parts of the surface being blasted out to create craters and large basins. Millions of years after these massive impact basins formed, [[lava]] from the interior flowed up to the surface through cracks in the crust and filled the basins. The lava cooled into the dark, volcanic rock [[basalt]], creating the lunar plains of today.<ref name="Lunar Rocks SI">{{Cite web |title=Lunar Rocks |url=https://airandspace.si.edu/explore/stories/lunar-rocks |access-date=19 September 2025 |website=[[National Air and Space Museum]] |publisher=[[Smithsonian Institution]] |language=en}}</ref>

Currently, basaltic rock, which is also fine-grained and rich in iron, magnesium, and plagioclase feldspar, makes up most of the lunar plains' composition. As with the distribution of the lunar plains, basalt is also not uniformly distributed over the surface of the Moon, with approximately 26% of the Moon's near side and only 2% of its far side composed of basalt.<ref name="Lunar Rocks SI" />
<!--


Because the Moon has no wind, water, or active volcanoes,




 the lunar plains do not experience regular notable changes, with most changes stemming from new meteoroids and other debris that hit the surface.

Breccia: The Smashed-Up Rock 
After the lunar surface cooled and hardened, an onslaught of solar system debris rained down on it and . Lunar sample ages suggest this period of heavy and violent impacts took place about 4 billion years ago. Since then, impacts have continued to shape the face of the Moon. Small ones still scar its surface today.

A breccia is made of irregularly shaped pieces of other rocks. Through time, meteorites crashing into the Moon have smashed, shattered, and shocked the surface, crushing and melting rock fragments together. Most highland rocks are breccias, which shows how widespread and important this process is on the Moon.

The Crisium basin is about 700 kilometers (430 miles) in diameter and is one of the many large circular lunar depressions. These basins or craters are formed by the collisions of very large meteoroids with the Moon.

==Nomenclature==

The modern system of Latin-based lunar nomenclature began in 1651, when Italian astronomer and Catholic priest [[Giovanni Battista Riccioli]] published ''Almagestum Novum'', an encyclopedic work in which he and fellow Italian priest and scientist [[Francesco Maria Grimaldi]] created a detailed map of the lunar near side's surface. In the book, Riccioli introduced a system differentiating lunar topography into three categories, with dark plains comprising one category and given Latin labels for bodies of water together with poetic, abstract names. Riccioli's system was used significantly in Europe in the succeeding centuries and became the basis for the current global standard in 1935, when the IAU adopted much of Riccioli's names and conventions. Since the current IAU nomenclature rules were affirmed in 1973, new names for lunar plains have been restricted to Latin terms that describe weather and other abstract concepts. Currently, there are 5 lunar plains' names referring to sea features, 5 indicating sea attributes, and 5 expressing states of mind.

Of plains inscribed prior to 1973 by the IAU, there are four that carry non-abstract names: [[Mare Humboldtianum]] and [[Mare Smythii]], named for German natural historian [[Alexander von Humboldt]] and British astronomer [[William Henry Smyth]], respectively;<ref name="Humboldtianum GPN">{{Gazetteer of Planetary Nomenclature|id=3676||name=Mare Humboldtianum}}</ref><ref name="Smythii GPN">{{Gazetteer of Planetary Nomenclature|id=3689||name=Mare Smythii}}</ref> [[Mare Moscoviense]], named for [[Grand Principality of Moscow|Muscovy]], a historical predecessor of Russia;<ref name="Moscoviense GPN">{{Gazetteer of Planetary Nomenclature|id=3682||name=Mare Moscoviense}}</ref><ref>{{Cite journal |last1=Martin |first1=Janet |date=26 September 2018 |title=Kievan Rus' and Muscovy Under the Riurikids |url=https://oxfordre.com/asianhistory/display/10.1093/acrefore/9780190277727.001.0001/acrefore-9780190277727-e-277?d=%2F10.1093%2Facrefore%2F9780190277727.001.0001%2Facrefore-9780190277727-e-277&p=emailA6bHCSURSHYnk |journal=Oxford Research Encyclopedia of Asian History |doi=10.1093/acrefore/9780190277727.013.277 |isbn=978-0-19-027772-7 |access-date=18 September 2025 |language=en |quote=[I]n the 15th century, those principalities coalesced to form Muscovy, the precursor of modern Russia.}}</ref> and [[Sinus Lunicus]], named for the Soviet space probe ''[[Luna 2]]'' ({{abbrlink|Colloq.|Colloquially}} ''Lunik 2''), which landed there in 1959.<ref name="Lunicus GPN">{{Gazetteer of Planetary Nomenclature|id=5566||name=Sinus Lunicus}}</ref><ref>{{Cite web |last1=Dutch |first1=Steven I. |year=2023 |title=Luna 2 Becomes the First Human-Made Object to Impact on the Moon |url=https://www.ebsco.com/research-starters/history/luna-2-becomes-first-human-made-object-impact-moon |access-date=18 September 2025 |website=[[EBSCO Information Services]] |language=en}}</ref> Because [[Mare Humboldtianum]] and [[Mare Smythii]] were established before the final nomenclature, they were maintained and not required to follow the name conventions.<ref>{{cite web|url=http://www.iau.org/static/resolutions/IAU1961_French.pdf|title=XIth General Assembly|year=1961|publisher=[[International Astronomical Union]]|language=fr, en|access-date=26 July 2015}}</ref> In the case of [[Mare Moscoviense]], which was discovered by the [[Luna 3]] and whose name was proposed by the Soviet Union, it was only accepted by the IAU with the justification that Moscow is a 'state of mind'.<ref>{{cite journal|date=22 August 2012|title=The name game|journal=[[Nature Magazine]]|volume=488|issue=7412|page=429|doi=10.1038/488429b|pmid=22914129|bibcode=2012Natur.488R.429.|doi-access=free}}</ref>
