What is a lunar crater? Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, almost all of which were formed by impacts.

The ejecta blanket from the Imbrium Basin (which was formed by a gigantic meteor impact) was returned by Apollo 14 and found to be about 3.9 billion.
The first complete maps of the Moon were produced from images obtained by orbiting spacecraft toward the end of the twentieth century. Illustrations of the surface of the Moon have been found dating before 3000 BCE, but the first true map of the Moon was produced by Michel Florent van Langren in 1645. This map portrayed lunar maria, craters, and mountain peaks. Latin names of seas and oceans.
The moon’s surface is riddled with craters ranging in size and structural complexity, and billions of years ago before life emerged, the Earth looked the same way. “The bottom line is, everything that happened on the moon happened on the Earth,” said David Kring, crater expert and team leader for Center for Lunar Science and Exploration. “The Earth used to look just like that.”.
Accordingly, previous studies of lunar crater morphology based on measurements of local topography and shadow measurements (e.g. Lunar Orbiter, Apollo) generally focused on craters with diameters greater than 10 km (Pike, 1974, Pike, 1977b, Baldwin, 1963, Baldwin, 1965, Elachi, Kobrick, Roth, Tiernan, Brown, 1976). However, the formation and degradation of SLCs are significant contributors to.
Lunar impact craters are important for studying lunar surface morphology because they are the most typical morphological units of the Moon. Impact crater descriptive indices can be used to describe morphological features and thus provide direct evidence for both the current state and evolution history of the Moon. Current description methods for lunar impact craters are predominantly.
Lunar Crater, a nearly circular maar, approximately 130 meters deep and 1,050 meters wide, is the most distinctive feature of the field. A second maar, approximately 550 meters wide and 65 meters deep, occurs at the south end of a northeast-trending chain of coalesced cinder cones. Several other northeast-trending alignments of closely spaced and coalesced cinder cones characterize the field.
Barringer Crater (Meteor Crater) in Arizona, United States, is a simple crater created when a 50-meter-wide (160-foot-wide) iron-rich meteroid struck Earth's surface about 50,000 years ago — a very recent event to a geologist. The crater is about 1.2 kilometers (a little more than 0.5 miles) across and 200 meters (650 feet) deep. Its features, such as the ejecta blanket beyond its rim, are.
