anomalies (red) bordering the Procellarum region overlaid on a global elevation map</figcaption></figure> <p>There are several hypotheses about the origin of Oceanus Procellarum and a related asymmetry between the near and far sides of the Moon. One of the most likely is that Procellarum was a result of an ancient giant impact on the near side of the Moon. The size of the impact basin has been estimated to be more than 3,000 kilometers, which would make it <a href="/wiki/List_of_largest_craters_in_the_Solar_System" title="List of largest craters in the Solar System">one of the three largest craters in the Solar System</a>.<sup id="cite_ref-:0_2-1" class="reference"><a href="#cite_note-:0-2"><span class="cite-bracket">&#91;</span>2<span class="cite-bracket">&#93;</span></a></sup> </p><p>The impact likely happened very early in the Moon's history: at the time when <a href="/wiki/Lunar_magma_ocean" title="Lunar magma ocean">magma ocean</a> still existed or just ceased to exist. It deposited 5–30&#160;km of crustal material on the far side forming highlands. If this is the case, all impact related structures such as crater <a href="/wiki/Impact_crater" title="Impact crater">rim</a>, central peak etc. have been obliterated by later impacts and <a href="/wiki/Volcanism" title="Volcanism">volcanism</a>. One piece of evidence in support of this hypothesis is concentration of incompatible elements (<a href="/wiki/KREEP" title="KREEP">KREEP</a>) and low calcium <a href="/wiki/Pyroxene" title="Pyroxene">pyroxene</a> around Oceanus Procellarum.<sup id="cite_ref-Nakamura2012_7-0" class="reference"><a href="#cite_note-Nakamura2012-7"><span class="cite-bracket">&#91;</span>7<span class="cite-bracket">&#93;</span></a></sup><sup id="cite_ref-Byrne2007_8-0" class="reference"><a href="#cite_note-Byrne2007-8"><span class="cite-bracket">&#91;</span>8<span class="cite-bracket">&#93;</span></a></sup> </p><p>Procellarum may have also been formed by spatially inhomogeneous heating during the Moon's formation.<sup id="cite_ref-Nakamura2012_7-1" class="reference"><a href="#cite_note-Nakamura2012-7"><span class="cite-bracket">&#91;</span>7<span class="cite-bracket">&#93;</span></a></sup> The GRAIL mission, which mapped the gravity gradients of the Moon, found square formations resembling rift valleys surrounding the region beneath the lava plains, suggesting the basin was formed by heating and cooling of the lunar surface by internal processes rather than by an impact, which would have left a round crater.<sup id="cite_ref-NASA2014_9-0" class="reference"><a href="#cite_note-NASA2014-9"><span class="cite-bracket">&#91;</span>9<span class="cite-bracket">&#93;</span></a></sup> </p><p>Other hypotheses include a late accretion of a companion Moon on the far side.
